It's symbolic to some Protestant churches , but not all.
Lutherans believe in the Real Presence, as do Catholics.
If you read the early Church Fathers, or theologians, those who were taught by the Apostles themselves,
THEY believed in the Real Presence.
THIS particular doctrine has Always given me difficulty.
I tend to trust the early Church fathers. But Jesus said THIS IS MY BODY, not THIS WILL BE CHANGED INTO MY BODY.
So, I'm not sure.
But here is what two early theologians believed:
St. Ignatius of Antioch (c. 110 A.D.) (He was taught by John the Apostle)
I have no taste for corruptible food nor for the pleasures of this life.
I desire the Bread of God, WHICH IS THE FLESH OF JESUS CHRIST, who was of the seed of David;
and for drink I DESIRE HIS BLOOD, which is love incorruptible. (Letter to the Romans 7:3)
Take care, then, to use one Eucharist, so that whatever you do, you do according to God:
FOR THERE IS ONE FLESH OF OUR LORD JESUS CHRIST,
and one cup IN THE UNION OF HIS BLOOD;
one ALTAR, as there is one bishop with the presbytery…
(Letter to the Philadelphians 4:1)
They [i.e. the Gnostics] abstain from the Eucharist and from prayer,
because they do not confess that THE EUCHARIST IS THE FLESH OF OUR SAVIOR JESUS CHRIST,
flesh which suffered for our sins and which the Father, in his goodness, raised up again.
(Letter to Smyrnians 7:1)
St. Justin the Martyr (c. 100 - 165 A.D.)
We call this food Eucharist; and no one else is permitted to partake of it, except one who believes our teaching to be true and who has been washed in the washing which is for the remission of sins and for regeneration [Baptism], and is thereby living as Christ has enjoined.
For not as common bread nor common drink do we receive these;
but since Jesus Christ our Savior was made incarnate by the word of God and had both flesh and blood for our salvation,
so too, as we have been taught, the food which has been made into the Eucharist by the Eucharistic prayer set down by Him, AND BY THE CHANGE OF WHICH our blood and flesh is nourished, IS BOTH THE FLESH AND THE BLOOD OF THAT INCARNATED JESUS. (First Apology, 66)
I'm sorry you are wrong about this, I looked into your examples, and while they are used by the RCC, as with many things taught by them these quotes have been warped and twisted to fit with the RCC teachings.
First
St. Ignatius of Antioch (c. 110 A.D.) (He was taught by John the Apostle)
I have no taste for corruptible food nor for the pleasures of this life.
I desire the Bread of God, WHICH IS THE FLESH OF JESUS CHRIST, who was of the seed of David;
and for drink I DESIRE HIS BLOOD, which is love incorruptible. (Letter to the Romans 7:3)
Take care, then, to use one Eucharist, so that whatever you do, you do according to God:
FOR THERE IS ONE FLESH OF OUR LORD JESUS CHRIST,
and one cup IN THE UNION OF HIS BLOOD;
one ALTAR, as there is one bishop with the presbytery…
(Letter to the Philadelphians 4:1)
In order to combat the false notions of Docetism, Ignatius and Irenaeus echoed the language Christ used at the Last Supper (paraphrasing His words, “This is My body” and “This is My blood”). Such provided a highly effective argument against docetic heresies, since our Lord’s words underscore the fact that He possessed a real, physical body.
A generation after Irenaeus, Tertullian (160–225) used the same arguments against the Gnostic heretic Marcion. However, Tertullian provided more information into how the eucharistic elements ought to be understood. Tertullian wrote:
“Having taken the bread and given it to His disciples, Jesus made it His own body, by saying, ‘This is My body,’ that is,
the symbol of My body. There could not have been a symbol, however, unless there was first a true body. An empty thing or phantom is incapable of a symbol. He likewise, when mentioning the cup and making the new covenant to be sealed ‘in His blood,’ affirms the reality of His body. For no blood can belong to a body that is not a body of flesh” (Against Marcion, 4.40).
Tertullian’s explanation could not be clearer. On the one hand, he based his argument against Gnostic Docetism on the words of Christ, “This is My body.” On the other hand, Tertullian recognized that the elements themselves ought to be understood as symbols which represent the reality of Christ’s physical body. Because of the reality they represented, they provided a compelling refutation of docetic error.
Based on Tertullian’s explanation, we have good reason to view the words of Ignatius and Irenaeus in that same light.
St. Justin the Martyr (c. 100 - 165 A.D.)
We call this food Eucharist; and no one else is permitted to partake of it, except one who believes our teaching to be true and who has been washed in the washing which is for the remission of sins and for regeneration [Baptism], and is thereby living as Christ has enjoined.

Justin Martyr (110–165) spoke of “the bread which our Christ gave us to offer in remembrance of the Body which He assumed for the sake of those who believe in Him, for whom He also suffered, and also to the cup which He taught us to offer in the Eucharist, in commemoration of His blood“(Dialogue with Trypho, 70).
Clement of Alexandria explained that, “The Scripture, accordingly, has named wine the symbol of the sacred blood” (The Instructor, 2.2).
Origen similarly noted, “We have a symbol of gratitude to God in the bread which we call the Eucharist” (Against Celsus, 8.57).
