Which Access Point?

Our existing access point is limiting internet speeds on most devices in the house - it's been there before we got a Starlink, so it wasn't a problem before, but is now. Looks to replace it, but not sure what to replace it with. Here's our setup:

• Starlink antenna on roof wired to Starlink router in attic. Gets about 300Mb down and 50Mb up to the router on average.
• Router networked to a little POE switch (this guy).
• Physical network connection from switch to TV.
• Physical network connection to Access Point (this guy).
• Everything else (18 devices currently) connect to that access point - all over 2.4GHz which is the only band available on the AP. If connecting to this via phone or computer, typically gets about 30Mb down and 10mb up.
• Office machine was running off a Powerline Adaptor connected to the switch until recently, but this now seems to be having issues dropping the Powerline connection. This got about the same speed as the Wireless AP, but more reliably for video calls etc. This is the main use case for the new wireless AP - to have a faster network connection to office PC.

The obvious choice is hardwiring office PC, and I will eventually, but we have some work going on that makes it impractical currently, so I'm looking at upgrading access point.

So with all above, is there any specific access point that would help us receive as much of the incoming internet speeds as we can wirelessly?
