I wouldn't question buying this game. It's a breath of fresh air and has lots of enjoyable elements. The music is also very well done, it's simple and relaxing. 10/10

There is a mod: https://www.nexusmods.com/valheim/mods/44
And there are more QoL mods.

Yeah I was going to say that I'm pretty sure that I saw a first person mod while I was digging through Nexus but looks like I'm a bit late to the party.

I highly advise digging through nexus mods as there are some objective improvements to be had.

I'd suggest get it, try it for an hour, see if you can handle the TPP. If not, return it.

I much prefer FPP, which I find MUCH more immersive but this didn't bother me.

No
Although you can scroll the mouse very close it is still third person.
