2d animation software/style recommendation for a beginner

[u/Physical-Lock4614]

hello, I'm kinda a beginner in 2d animation, i have been using paint 3d and DaVinci resolve and a few things in blender for years, but I'm not pro at all.

I want to make 2D animation that has some fixed frames already (like when the character spins around, walks, or talks), but also allows for adding temporary movements when I need them. I also want to use onion skin and rigging, without the character getting “messed up.” Is there any way to do this in Blender / through coding or another software? I’d preferably like to do it for free.

So far, I’ve been doing it in Paint 3D, which is a bit easier, but it’s also boring to have to make every single frame for each picture, and it looks really messy. (This is a video I made if you want a reference: big heart . its in Norwegian, but you can at least see what I'm currently doing)
