Maxillaria Tenuiflora x Variabilis should I repot or leave it?

[Orchid-Obsessed]

I received this Maxillaria Tenuiflora x Variabilis, yellow coconut scented orchid, in the mail yesterday. It arrived in a 3” pot, in sphagnum moss. There was what looked to be date on the pot “0319”.

Should I repot? Should I leave it as is- but put in a same size pot because the pot it came in only has the bottom drainage hole, clear plastic and very soft, flimsy.

Should I pot it up in a size bigger or no? That means leaving it in moss, right? Can I leave the all the moss intact since it’s root bound anyways and fill around the sides with bark, charcoal, lava rocks? Or do I need to fill the sides with moss?

Why do I wish to repot? I’m afraid that if I don’t repot to a bark mix, I’ll over water. I’ll kill it. I read ‘just wet or moist, but not soggy’. How do I water without making the moss “just wet, not soggy”?

Why are the pseudobulbs wrinkled? Bad roots in the middle, dehydrated? Can I get them to plump up again? How? I also read to leave the bottom of pot in a saucer of water in the summer, is this when it’s potted in bark mix only or is this applicable also if potted in moss?

If I repot, do I remove the moss (seems impossible because root bound, I tried but afraid it’ll severely damage the root) ? is it possible to repot without causing too much damage to the roots because it’s root bound? How do I do that, pull each plant apart in groups of 2 or 3 keeping the root intact as much as possible? It I repot, should I use bark, lava rocks, charcoal and moss.

Growing in a portable greenhouse under COB LED grow light-1200w, humidity range 55-65, summer temp range 28c to 30c daytime, night time 18-22c.

Please provide me with advise, I’m really stomped on what to do, I’ve waited 6 months to get a yellow scented orchid-I only started orchid growing hobby. I’ve watched lots of YouTube videos, read forums here which I wish I could bookmark to read again, but still unsure as to how to proceed..thank you very much.
