I don't think you can combine what are essentially business products (wall/ceiling mounted APs) with consumer products mesh. You'd just have to use the standard method of using the same SSIDs on multiple APs.
Like you said though, how you have it now is likely good enough. Almost all my devices spend 99% of the time in the same room as the AP and as I have a Steam Deck having the fastest AP I could get worked out well, it can download at 82MB/s. But if you have nothing where speed is important, you might as well wait a few years for WiFi 7 to be finalised and upgrade then.
