In San Diego, AT&T Fiber is the fastest option (symmetrical up to 5 Gig) and the top overall pick — and for cable, you'll typically have either Spectrum or Cox depending on your part of town (rarely both), with both reaching up to 2 Gig.
San Diego is unusual in that its two cable providers — Spectrum and Cox — divide the city, so most addresses get one or the other, not a choice. AT&T Fiber is the speed leader where available, with no data caps; Spectrum also has no caps, while Cox applies a (large) data cap. T-Mobile and Verizon 5G round out the no-contract options.
