LFP I know about, and they can provide more than 2000 cycles if you make the same sort of effort as one does with Lead. Charge them right, don't run them too low, ask too much of them when they are cold, etc. You can ruin any battery. There is a loss of capacity if LFP just sit, of maybe 1% a year (I am reflecting some stuff I saw on EVTV), number of cycles does not degrade. I make a distinction between the aging/degradation and misuse.
