I'm possibly not the best to answer, as I always aim for the most "frugal" option. However, I'm running two GT Omega Art -series cockpits right now. One is assembled and complete, but is my driving sim. The second will require me to buy a few more parts from GT Omega (once their Canadian store opens back up, I believe a member here said they could help as an intermediary if you need things very soon from the US site), but they Do exist and are specific to flight/space sims. A hotas/hosas bracket kit, a platform to add a small keyboard and mouse on the main platform, etc. I bought both my ART cockpits as just the bare frame, SIM/racing seats from cars are fairly cheap from the used market (But, y'know, clean them really well before use haha) so it doesn't cost an arm and a leg to get set up. My driving sim only cost me a few hundred (excluding the Fanatec stuff! Obviously haha), maybe like $500 for cockpit, used TV and a Used seat. Really not bad for a "starter" setup.
Quick PS: I picked the ART series from GT Omega because it's the only cheap cockpit that has vertical supports for the main platform (where my direct drive + wheel attaches). It's might not be as big as deal for a space sim, but I found other cheap cockpit stands that didn't have that vertical support very flimsy and not worth it.
Good luck and let us know what you do!
