Trying to get Wi-Fi to detached garage for home office (alien.top)

TLDNR- Wifi setup to get signal to 25x30 garage 60 feet from house, service comes in first floor 50 feet further from back of house.

Woe is me. Sorry for yet another question.

We have 1000MBps AT&T fiber. Using the Wi-Fi built into the gateway, we barely get a signal to our detached garage.

I failed to add ethernet when I trenched to run electric. Prefer not to because of grounding issues and now there is a sidewalk crossing the backyard.

Currently the fiber connection comes in towards the front of the house. It's about 50 ft from there to the back of the house. Yard is another 60 ft. Then garage is about 30 ft deep.

Just purchase a set of ASUS XT9 Zenwifi. In testing inside the house I'm only getting around 150 to 160 Mbps on the AT&t gateway Wi-Fi. XT9 is only 100Mbps

If I place the node in the back window of the house, I can get 30Mbps at the closest part of the garage, 10Mbps at the farthest.

Do I need a 3 router system? I could probably run ethernet backhaul to the back of the house, but I don't know that it will solve the issue.

I tried to talk one of the ATT fiber techs into running me an aerial fiber cable between the two buildings but no dice.

I know a lot of things are on sale right now so hoping I can get advice and get something still on discount.

Current thoughts -

XT9 is not getting a strong enough signal to the garage.

For time being I have a set of TPLink AV2000 Powerline adapters, Speedtest is only pulling 50/50 Mbps , which should be enough for office work in the garage.

Long term will probably try to improve with either an aerial Fiber run or a PTP Wireless setup(more likely).

I could keep the XT9's(on sale at $350) for this setup, but is it(and any mesh setup) overpriced/a waste if I am using either wired or PTP for backhaul? If so what would make more sense device wise? I could just run the house of the ATT BGW320 Gateway and get a single AP for the garage, or get a matched set of routers.

If I go PTP I would need something that supported POE or would need to add a POE switch.

I'm testing with a Pixel 7 and and Framework PC(Intel® Wi-Fi 6E AX210) which both support higher speeds than I am seeing right next to the routers(~250-400 / 300). Is that just the reality of 'top' speeds vs actual? If so does it make sense to back down my ATT service(we do have multiple users and everything is wifi)?
