Is Jesus seen as both the Passover Lamb and Goat(s) of the Atonement in any Protestant Theology? It is often said that Jesus fulfilled the Jewish spring feasts when he first came and the expectation is that he will fulfill the fall feasts when we returns.

Also, that Jesus died at the time of Passover reinforces that he was at least understood as the perfect Passover Lamb.
See: How does the Passover foreshadow the coming of Jesus as the Messiah?

However, it seems to me Jesus also fulfilled at least part of the Day of Atonement (in the Fall season) where one goat dies and the other receives the sins of all the people(Is. 53:6) and then it is led out of the city, away from the people, removing their sins far away.

Many people will often compare Christ to this scapegoat but I have yet to find any fuller treatment of how Yom Kippur was fulfilled in Christ's first earthly ministry rather than his second coming.

Are there any Protestant/Reformed, or older, writings that deal with Jesus fulfilling the prophetic nature of Passover and Yom Kippur?
Either affirming or denying, but specifically speaking to the concept of "fulfillment" of the two feasts in Jesus' first coming.

This may include catholic works, particularly from the early church, prior to the Reformation as well.
I would expect that every Christian denomination would see Jesus's death as the fulfilment of both the Passover sacrifice and the Day of Atonement sacrifices and rituals, because the identification is made in the scriptures themselves.
1 Corinthians 5:7 says directly that Christ is our Passover lamb:

Cleanse out the old leaven that you may be a new lump, as you really are unleavened. For Christ, our Passover lamb, has been sacrificed.

Hebrews 9 is a lengthy comparison of the Jewish priests' ministry and Jesus' ministry. Its focus is more on showing that Jesus is the great high priest than explicitly saying he was the fulfilment of the goats, but the comparison is still there when it talks about his blood. The first paragraph shows that the Day of Atonement was the focus. The second shows the glorious truth that Jesus' death has done away with the need for all recurrent sacrifices!

Hebrews 9:6-7: These preparations having thus been made, the priests go regularly into the first section, performing their ritual duties, but into the second only the high priest goes, and he but once a year, and not without taking blood, which he offers for himself and for the unintentional sins of the people.
Hebrews 9:11-14: But when Christ appeared as a high priest of the good things that have come, then through the greater and more perfect tent (not made with hands, that is, not of this creation) he entered once for all into the holy places, not by means of the blood of goats and calves but by means of his own blood, thus securing an eternal redemption. For if the blood of goats and bulls, and the sprinkling of defiled persons with the ashes of a heifer, sanctify for the purification of the flesh, how much more will the blood of Christ, who through the eternal Spirit offered himself without blemish to God, purify our conscience from dead works to serve the living God.
