there isn't one, not in the FOSS world at least, Etar is just the old AOSP Calendar that Google abandoned but updated, but it still uses MD2 for it's design, Fossify Calendar attempts to say it's MD3, but in reality it's MD2 shaped to look barely like MD3, but hey, at least it uses ur Material You color palette, not the correct shades, but adjust ur expectations a bit /s

this is the entire reason i was working on my own proper MD3 calendar for a while, and frankly, i should still get around to making it

best ur going to get is probably Google Calendar, but well, that's Google, and Proton Calendar, but well, that's Proton

@I lost my account, so I'm here now I guess I have an older Samsung Tab here and I was able to create and update events in my calendar through the default app Android provided. Please note that the app has its own "private" calendar which is a local one and not synchronized. If you use the recommended connector by Nextcloud client, you need to choose that calendar. Then it gets synchronized here.
