I'm not giving any advice either way, but I have signed a 2 year lease in the past although not in CT. I had just moved to NYC and was relieved to find an apt without having a guarantor (something commonly requested in the city) but the landlord wanted 2 years. We agreed, and it ended up being fine. It does make it more complicated if you need to move but it also helps protect you from a rent increase for that extra year. (We did end up having to break a lease later during Covid when we left the city but were as helpful as we could be with getting new tenants. Of course that was an unusual situation so your mileage may vary.)
