Sure, you can print minis with an FFF machine. But there’s a reason the mini printing folks primarily use SLA. For that particular application, it’s significantly better. I say this as someone who uses an Ender 3 and is quite happy with it. If my main goal was printing minis, I would probably want an SLA machine instead.
If your goal is to make mini figures, what you want is an SLA machine. They are much better at making small detailed objects than FFF. However, it will definitely cost more than a cheap FFF machine like an Ender 3.
The Ender 3 variants are cheap and a great platform if you are OK with tuning/tweaking things. If set up properly they work great and are pretty reliable. But of you want something that works out of the box and doesn’t need any tweaking/tuning, you will probably be disappointed with it.
This is why Google has been using their browser monopoly to push their “Web Integrity API”. If that gets adopted, they can fully control the client side and prevent all ad blocking.
FreeCAD definitely has a steeper learning curve and a few rough edges, but to me it was absolutely worth it to learn. I really don’t like my files subject to the whims of Autodesk.
