What you miss, my FRiend, is that the Cross was not the scene where forgiveness took place. That was just the killing zone, and it was on earth. It was the place where Jesus' Blood was separated from His Body and gathered for the use at the place of atonement.
The forgiveness took place in Heaven, when His Blood was placed on the True Mercy Seat in the Holy of Holies there, and presented to the Mighty God to compensate for mankind's sins from Adam on, thus satisfying The Mighty God's Righteous Demands, and thereby placating His Just Wrath, with the consequence that peace was made by mankind's representative, Jesus Who was/is The Eternal High Priest. Having then completed His period of voluntary service to The Father, He was able to again take up the glory He had lain down, and be seated in His role of acting as Deity with God The Father, and ask for the Comforter to be sent to earth to govern His saints.
Again, the forgiveness took place in Heaven, not at the Cross, but rather after His ascension on Resurrection Day, in Heaven. But the Cross-death was absolutely necessary for the killing and bleeding that produced the precious Blood of Atonement in Heaven.
"Today you shall be with me in Paradise."
On this, I will go along with your reading of the metaphoric and symbolic application of the Blood in Heaven...
Which leads to the flaw in your argument that Christ bled out physically and had no blood in His body at the Resurrection.
The application of Christ’s blood is symbolic (not strictly physically applied) but binding.
The prooftext for your argument would be that the sacrificial animals of the Levitical priesthood would have to be absolutely drained of every last bit of blood.
I don’t recall that being a requirement. In any case, see my last posts as to the medical reasons for Christ’s death on the cross.
He did not bleed out.
