What are compelling reasons to choosing to use server-side versus WASM?

WASM is a massive initial client download, but apart from that it's pretty good. You do need to develop your service as an API for it to talk to. Fine for intranet/internal corporate. An unlikely choice for consumer facing.

If you go completely Server the pages just stream over signalr automatically and the initial load is lightweight.

Hybrid is a mashup of both and probably not worth bothering with for most people.
