I've gotten a pretty reliable 400-500mbps over a "2gbps" powerline adapter. Granted this was in small 1-2br apartments, but you're probably dealing with only one coax jack in the whole place and it's not feasible/worth it to run your own cabling.
Imo, in a small 1-2br apartment it's easy enough to run ethernet and hide it along the walls, either by tucking it under the moulding if you have carpet, or using cable hiders.
I'm also just laser focused on good consistent latency though after years of suffering awful cable internet and trying to minimize all latency that I could control (https://i.imgur.com/i84mIsD.png was what it was like during the day in 2020 in the first wfh period. Luckily I've only been getting consistent spikes up to ~200ms throughout 2021 /s).
edit: That ping was on hardwired ethernet with no load as well, and Rogers (realistically the only ISP where I live in Canada because my available Bell DSL connection is too slow) was throttling uploads to 4mbps.
My go-to solution for routing ethernet while renting are 3M Command Hooks. They are remarkably strong, while being easy to remove – albeit a tad bit on the expensive side.
