Same; this was the nicest unexpected surprise about buying this place.
Condo built in 2006 with cat5 . Two bedrooms + living room all wired with rj11 phone jacks. Just snipped those off, wired up rj45, and attached the other ends in my utility closet to a patch panel with rj45 as well.
I don't know if it's just cat5 or 5e, but it saturates a 2.5Gbe link and in-wall cable length is about 15-25 meters.
And you're lucky with that build time, if it was more recent it'd probably be CCA or even CCS. When we redid our place a few years ago I went and bought a drum of plenum cable and told the electricians to use that, so I know what went in there. Overprovisioned slightly but who cares, I had a whole drum of cable and a 48-port switch so may as well use it all.
