What do you use to recharge the battery?

760CCA Group 31. I would use either a Trojan or East Penn/Deka. No need for a dry cell.

I would use a regular wet cell. The AGM is like 3x the cost. Deep cycles are almost 2x as much. If you are just winching, it will be like a start application for the battery. It is designed mainly to drop tons of amperage when starting a big truck. If you were using a smaller automotive sized battery you would be cycling it much deeper than the group 31. If you are going to use it for other things (stereo, lights, etc) while not a charger, then consider a deep cycle.

You can use one. But look up a East Penn Deka 1031 MF battery. Should be available for well under $100 at any big truck stop, repair center, or a battery supplier. Make sure to only get the 760CCA battery (it actual will test around 1000amps). The 760 will last longer than the higher CCA batteries. The 1031 is less money, and will last 2 years longer on average. (Because the plates are thicker)

4ga is a bit overkill, likely 6g will work fine. The battery if really down will accept 50ish amps for a couple of minutes and then drop off fairly quickly to 25amps. So really heavy cables are not necessary. But bigger is better, so dont let me discourage you from the 4ga. You can get Anderson Ends in 4 and 6ga as well as really heavy guages. If you go with 4ga, and use Anderson Ends, you can use the hookup for other things too, like a booster cable, 12volt outlet, etc.
