Can Cat5e do 2.5gbps?

Recently moved in to our first home we just bought. It was built in 2018 and I thought it had ethernet wired round the whole house but upon further inspection its actually BT phone connections. They all terminate at the same spot where our Fibre modem is. we had an engineer from openreach come to upgrade the modem so we can get 1.6gbps, I asked him about the connections and neither of us could understand the point of BT phone connections in a new house built these days. He said if I was lucky it might be either cat 5e or cat 6 cable with only 1 twisted pair used. He was correct, I took of one of the face plates and could see printed on the cable was Cat5e. I've seen online that you can only get 1gbps over cat5e, but I thought it was possible to get faster over shorter runs?

Am I right or is there no point paying for over 1gbps. (wifi in this house sucks even when using a wifi7 mesh)

It's the error rates which will be higher in lower quality wiring but yes it's not noticeable on short domestic runs.

I did try to have a look at what little I could have the cable to see if there were any other markings. They came from a local supplier, found the website but no good information other than it really just being bulk Cat5e sold for trade. I can't imagine there's runs any longer than 10-15m. the most important room I have my PC in is directly above where it all terminates anyway

2.5Gbps and 5Gbps were both designed with the express aim to get faster speeds over existing Cat5e cabling (rather than having to rip it out and replace with Cat6/6A). As such you will be absolutely fine, especially at the lengths in a typical home network.
