Are you planning on entering an ecosystem? I set up TP-Link Omada in my home. I have a router/firewall, AP controller, switch with PoE ports, and 2 APs.
Firewall: https://www.amazon.com/dp/B08QTXNWZ1?ref=ppx_pop_mob_ap_share
Switch: https://www.amazon.com/dp/B08J9ZQ7HC?ref=ppx_pop_mob_ap_share
APs: https://www.amazon.com/dp/B0781YXFBT?ref=ppx_pop_mob_ap_share
AP controller: https://www.amazon.com/dp/B08SW3GFHH?ref=ppx_pop_mob_ap_share
If you are going with TP-Link equipment, choose the ones you can manage with the Omada controller.
ER605 that you decided on
TL-SG2210MP managed switch with PoE
EAP610 access point that is WIFI 6.
Then you would need the controller, that you can install on a PC or Pi, or you can get the OC200 hardware controller
This will enable you to control all the devices in a single web page.
This is what my enclosure used to look like, before I upgraded to some much beefier / rack mountable hardware. Upper left is an 8 port gigabit switch, lower left is my USG3P router, upper right is an HDHomeRun Connect TV tuner, middle right is my cable modem, lower right is an Insteon Hub).
In your case, if you've already got all the ethernet runs to your panel (or run to the location where you will have the panel), I'd switch your router for something like the TP-Link ER605 (or some similar wired-only router). Then install a switch that is small enough to fit, but has enough ports for the ethernet runs you've got. Your modem / ONT can also be located in this space.
Then, you can set your routers for AP mode, and place them wherever in the house they need to go. Personally, I'd sell off the routers and switch to APs instead, but the routers you've got would be more than adequate for AP duty.

I've since upgraded my router to a UDM-PRO and my switch to an unreleased version of the USW-24-250w (which I received for free in exchange for helping test a hardware change they were thinking about making, but later abandoned). Both now live in a rack I custom made, along with a UPS, to keep the router / modem / switch powered during short power outages (the rack lives just below the structured panel).
You could put the two routers you have in AP mode and replace the switch with a ER-605
A very cheap solution is to buy a TP-Link ER605 Multi WAN router and set the mesh system to AP mode if that is possible for your mesh system to avoid double NAT.
Thank you so much for the quick answer! You seem to know a lot about this so I'll ask a quick follow up. Since the goal is to move the Wi-Fi point out of the closet, would this TP-Link or this Ubiquiti EdgeRouter X allow me to then run the Wi-Fi point from another ethernet jack? I figure I don't need anything fancier than that since the Google Wi-Fi already covers the wireless network aspect. Thank you!
Here is a router that's both business class and very easy to set up. Has options like having multiple ISPs so if one goes down, it automatically goes to another, QoS, load balancing and is plenty powerful enough for a home setup (being business class) while also using significantly less power than an old PC turned into a PFSense or OPNSense setup, while also only being $60.
After debating on which way to go for a few weeks, I ended up with that router and I'm beyond happy with it. I have a USB stick in it for backup of my settings and logs (if something messes up) in case anything happens with it.
I didn't use a ubiquity router. I used a TPLink ER605 and some wireless access points.
