Zynthian (a RPi-based synth collection & groovebox) lists some of the most prominent ones on its website: https://zynthian.org/engines

Its install recipes directory may yield a less fancy, but probably more comprehensive list: https://github.com/zynthian/zynthian-sys/tree/oram/scripts/r...

With Zynthian OS up and running, the full list of plugins shows in its webconf page, it's so long that they have to hide basically most of the plugins from the main on-device UI.

Roughly speaking, if it's open source, most likely it will work. If it's proprietary, assume that only Pianoteq and a small number of u-he plugins will work. Most commercial products with binary-only distribution don't feel like RPi devices are a large enough market for them to build binaries for it. Even if they otherwise offer ARM builds for Apple Silicon and Linux builds for x86.
