Upgrade Question(s) [sorry for length]

Recently (beginning of summer 2024) I got a Logitech G920, built a wood chassis, and have been playing FM8, FH4, ACC, and F1 24 on XBOX Series X with it. I quickly realized I loved doing laps on tracks by myself along with AI racing, but have been limited in terms of multiplayer by the cost of XBOX Game Pass. Currently I have driven enough on my games that, personally, I feel I am becoming limited in comfort and performance by my rig (I know plenty of people race well with a G920, but I went to a sim cafe near me and my lap times were immediately better with the smoother/more FFB and load cell pedals).

So, I'm looking to upgrade my rig (kind of replace?) to something that will be more comfortable and bring me even more enjoyment, but will also last hopefully close to the next 5 years with only a few upgrades (sticking to XBOX [mentioned later] will be different)

Question 1: Should I make the jump to PC (is it really worth the $1,400+) or stay with XBOX? I would like to make the jump at some point, so I guess I'm asking if I should do it now or hold off?

Question 2: If I jump to PC, what kind of GPU do I need for 3x32" 1440p monitors? I'm looking at (currently) 7800XT, 7900 GRE, or 4070 super (all with a 7700x or 7600X3D; which one is better, or neither?). The only problem I have is that the price of a PC in addition to a new rig makes my eyes water.

Question 3 [lazy? Pictures attached!!]: Q3a: If I get XBOX components, I'll probably move to PC & XBOX within a year or two, maybe even switch to a full PC setup. I'm thinking of going with Logitech G Pro (heard nothing but good things about it, I don't mind the small ecosystem) and MOZA CRP2 pedals all on a SimLab P1X Pro and single monitor stand (upgradability in the long run, especially if I later go to PC) with a 34" 1440p monitor. This is currently what I'm leaning towards doing! Opinions?

Q3b: If I go to PC, I'm thinking of going with a Simagic Alpha or Alpha U (Microcenter sale!) with a Simagic GT Neo wheel and MOZA CRP2 pedals all on a SimLab P1X Pro with a triple monitor stand and 3x32" 1440p monitors. Opinions?

Question 4: Any other suggestions? I'm interested in hearing what anyone has to say from personal experience or research. If I go to PC, I'm looking into iRacing and BeamNG Drive, but can I download the XBOX app and still play my games I have on the "cloud" so I don't have to buy them again?

Any other questions I'll probably add in a comment and I'll be responding to your guys' comments :)
