My favorites are TP-Link's WDR3600/4300, AC1200 and AC1750. Yeah, not switches per se, but $20-40, Gigabit Ethernet, dual band Wifi, very stable and fast with OpenWRT, can do anything. You can daisy chain a few of them if you need more ports, it's rather fun.
If you really are futureproofing, note that most AX (Wifi 6) equipment today doesn't support the new 6ghz frequencies recently allocated to wifi. For that you need "Wifi 6E". Of course, 6E stuff is quite expensive right now. (Expect to pay $400+ per node)
Heh, I only have 4 of them and they're not going out of use anytime soon. Bought all of them used, of course.
One works as a main router for a fiber Internet connection (via a dumb SFP-Ethernet D-Link switch), 2 handle the "Intranet" 1 house + 1 workshop (Wifi bridge via one band) computers, printer and NAS, and one is with me, acting as a repeater bridge.
If I buy anything new it'll habe to support OpenWrt or I stick with AC1750s lol.
Even Wifi N 300 is enough for my needs, computers are wired and my phone doesn't need AC speeds.
The EAP660 is pretty good. I replaced a few mesh routers with a single EAP660 on a second floor ceiling. I like that they allow you to run a single one without a controller. I'm happy to no longer tie my router to my access point as it was getting to be a bit too much effort to make changes or upgrade before I split their roles. No WRT support, but I don't think that's a concern for just an access point.
The AX series is the current TP-Link offering for most use cases starting at ~$80: https://www.newegg.com/p/pl?N=50012120%20100158096%206013568... In addition, the AX3200 Belkin (RT3200) is $100, and the $140 Linksys (E8450) are both listed as supporting OpenWRT.
