It is most likely fine. As others have pointed out, PEX comes coiled and it is completely acceptable to have it installed with curves and arcs, like this:
PEX is not like copper or iron pipe. Rigid pipe is... well... rigid, so we get used to thinking of plumbing as begin built from straight sections, but that isn't the case with PEX. I'm assuming the ...

I'm from the prairies! Haw! We have gophers like crazy here and I've never heard of them eating into electrical pipe.
For ease of pulling and overall durability I'd consider using rigid PVC or direct burial pipe. Pex quality often varies as well(I've seen batches sent back for being too brittle in winter, too soft in summer, for having too thin of wall. ...

23 gauge hardware cloth strikes me as something that won't have a long life when buried in the ground.
I'm no gopher expert, but taking your word for it that some protection is needed even at 30" depth, I'd think about encasing the PEX and cables in something else:
solid-core SCH40 or even SCH80 PVC conduit or pipe. Not SCH20, class 200, nor foam-core ...

There are reasons that they are not readily available. And it is because they shouldn't really be used in most cases.
Having 3/4" water pressure times 2 (hot/cold) is going to blow out filters and gaskets for toilets and sinks which are not really manufactured for that much water pressure.
I had a sink at my old house - which had bad water pressure in ...

You can keep it all 3/4 PEX, or you can reduce it to 1/2 to save money and space, or to deal with parts availability.
Most fixtures (sink, toilet, tub, shower) don't need 3/4 all the way, but it is not forbidden or bad to do so.
When branching off, you can use a PEX Tee fitting that also reduces. You can branch off at 1/2 at each fixture, and continue with 3/...

"Need" is defined by the connection you want to make. As you've discovered, shutoff valves (supply stop valves for use with a fixture) with 3/4" inlet practically don't exist. Therefore yes you'll need to adapt the plumbing to the inlet of whatever shutoff valves you can find. Shutoff valves are widely available with inlets of either 1/2" ...
