How do people find mods/worlds that are compatible?

[josephdpurcell]

I started working on a list of compatible mods/worlds here: #439

I was on a roll with maybe 5 downloads from Curseforge, then the next 15 were busts. I'm curious: how do people find compatible mods/worlds? I've noticed the ones that work have db, resource_packs, behavior_packs folders, and the ones that don't work have folders like data, datapacks, playerdata. Perhaps at a glance this is how to tell the difference between Java vs Bedrock edition mods/worlds? But, if thats the case why doesn't Curseforge filter based on this criteria, or am I just not using Curseforge's website correctly?

Any thoughts or help is appreciated!
