First timer, should I run a PVE build first?

I don't really know at all.

Yes crafter/pve build should be first thing.
Look in the survival guides section and you will find a lot of good starter guides and builds and info for everything. Use whichever you like best since all those you posted look credible. They explain the basics and just look around or use the wiki and you will have all the info you need to do everything in the game.
Just watch out for how old some are as they may be a little outdated.
