Help me install windows 10 iot ltsc?

Hi guys, noob here. I recently bought a new pc and it came with windows 11 which i do not like at all. I would have liked to install Win 10 as soon as i bought the pc but it's about to reach end of support. So i thought i would do an install of windows 10 ltsc but i'm confused.

I did read the megathread but it seems like it's mostly about debloating the iso file. I don't really mind a little bloat, and it's way less compared to 10 pro anyways, i just want to know if i can download the IoT iso from massgraves and use rufus to create a bootable. Can i also use MAS to activate IoT or do i need to buy a key from Microsoft? Also, do you think i should go for IoT ltsc or enterprise ltsc, which one is friendlier and won't crash if something goes wrong? TIA
