you should give blender a go. I started game dev last year in September so i'm sill learning but for all my models I use blender. Blender is highly recommended, it's free and there are tons of tutorials about it on youtube plus if you download a 3d model from lets say sketchfab and you need to import into unreal but there is no fbx or glb format download it and import it into blender and export to fbx or glb. Just my opinion though but blender highly recommended. Hope this helped. And if You ever need a lighsaber model just go to tedpiko.itch.io. :)
