Bandwidth:
2.4 GHz: 20 MHz (there's also a 20/40 MHz option)
5.0 GHz: 80 MHz (there's also 20 and 40 MHz options)
If those options do what I think -- 80MHz bandwidth implies using four 20MHz WiFi channels in parallel. I suspect the R-Pi hardware doesn't support that. Might not even support 40MHz (two channels in parallel).
I'd suggest trying to set the 5GHz settings to 20MHz and retrying all your devices. Then maybe 40MHz and repeat.

Thanks for the suggestion, but I'm not using the 5 GHz setting for my hotspots. I'm selecting the 2.4 GHz option, and in my router, that's set to 20 MHz.

Thats why I mentioned both of those configuration settings. Since band steering is enabled it might be trying to move your 2.4 Ghz connection over to 5 Ghz, and our connection issues might actually be the same. If you share the same SSID on both bands you might not realize its tried or moved you over to 5 Ghz. Like on my setup I would see that it moved from one SSID to the other one labeled 5 Ghz.
Okay, first I'm going to try turning off Band Steering to see if that makes a difference. I can't find a setting to combine the two band's SSIDs.
First try with Band Steering turned off and Pi-Star set to use the 2.4 GHz band worked just fine. So maybe our two issues are the same? I'm a little bit reluctant to try the 5.0 MHz band just because of what a headache this issue can be, but for the sake of science I'll give it a try.
Okay, with Band Steering turned off and Pi-Star set to use 5.0 GHz band, it took two power ups the first time. Will keep playing around with this for the next day or so to see if a pattern solidifies.
UPDATE: Tried once more with Band Steering turned off and Pi-Star set to use 5.0 GHz band: took three power ups. AP didn't work on the first two attempts. Switched back to 2.4 GHz band, and it connected first try.

Separate Wi-Fi SSID
I've looked everywhere in the AmpliFi app and have not found an option with that label. Maybe that's one of the differences with the Gaming version of this router? Either that or I'm just not seeing something right in front of my eys.

Sorry for sending ya on that wild goose chase.
I really appreciate all your suggestions and help. It seems like your suggestion to turn off Band Steering has already made my life much better, as I'm no longer having issues with my RPi 4B+ based hotspot connecting to my wireless network when it's on 2.4 GHz. So I'm just going to steer clear of 5.0 GHz for the time being.
I installed the latest firmware update for the AmpliFi, so it appears that the manual is a bit outdated. Not the first thing that has disappointed me with Ubiquiti. Ah well, you never know until you try something.
