Wi-Fi extenders

Try having it higher with a cable extension. Sometimes that's all you need to clear all the clutter around you.

Try using a 6ft usb cable with female end connector for your Wi-Fi device, then raise it to ceiling height or move to to a window

I have recommended and used the Netgear PlW1200 - it's a different take on an extender. You connect one end of the unit using an ethernet cable into your router/Cablemodem. You plug the other end into the Netgear device, and that unit then plugs into your 120Volt wiring. The other end, you plug into your 120v wiring in the house, it has an ethernet port as well as wireless.

In essence, it's using the wiring in the walls of your home as "network cable" to extend the signal to the other unit on the other side of the house.

I have a friend who has one in his garage (about 200' from the house) and he's getting 900Mbs sustained to his home network storage device (NAS) as well as the same response as he gets inside his home.

It's a simple solution and works well.

I think you’ll find the mesh systems like you bought will be the best solution. I use the Eero, and it works great.

Another suggestion, is if you can run wired connections, hire someone to run some Ethernet cabling to fixed location items. I run all my smart TVs off off wired connections, and also have a couple of places I can plug in my laptop when I work from home. A wired connection will always be faster and more stable than wireless.
