PlayStation controller controls kind of rough

There are a couple of issues I am having. I think I am having a few problems just because I prefer to play with y-inverted on. I expect to look down when I push the right stick forward so I usually toggle that. Especially since this game has flying I think this should be supported and it is, sort of. There is a separate airship y-inverted toggle, but these don't seem to be in parity. Y-inverted makes it so the airship noses down when you pull back on the stick, which doesn't seem right.

For some reason y is also inverted in the build menu which is controlled with the left stick. This is really baffling as movement is normal, it's only the build menu that's affected. This has made using the build menu difficult. Accessing the outer ring is especially challenging.

Free look while flying requires you to press on the right stick. This is a problem because the same stick also is the look control. Actually trying to look causes the button to relax and then snap out of free look mode back to forward at Mach sick.

Can anyone tell me how to access decoration variants? I have been using default decorations until now, but I really want a cooking station and the recipe has a non-default variant, a pot, as an intermediate step. I see the variant on the crafting screen, but I can't find the control to select it.
