Is that Auburndale, FL? Your local terrain could influence suggestions so it helps to know exactly where you are and how you use the jeep. For the 3.6L and 35s with an auto, typically 4.56 is the sweet spot, but there are cases where leaning to 4.88 could be in the cards....like if you live in the mountains.
If you're planning to purchase wheels and it's not too late, most of us would suggest a 17" wheel instead.

Resharp001 nailed it ...
If it is honestly a DD for 90% of the time, the 4.56 ratio is the one to go with for comfort and gas mileage.
If you’re going off the asphalt, go with the 4.88’s - in my opinion, Offroad means go with a deeper gear set - it’s just kinder to your Jeep !

Understood on trying to re-use the current wheels, they'll work fine.....more of a thing if you were going to purchase wheels and a 17 would be better than buying 18.
Nobody is ever going to complain about the extra low-end power that a lower gearset will give them, so with the 4.88s it's going to be a question if the high-end engine revving will bother you or not. With 35s (which will likely measure more like 33.5-34") the engine would be running close to 2900 RPM @ 70mph. If you drive faster on the interstates then you're easily up over 3k RPM. That may or may not bother you. I would suggest that during some normal highway driving, you force that auto into some lower gears so that you are running in that RPM range and just see how you feel about the engine sound.
I've driven on a tire/gear combo that put me in that rpm range on the highway. It does get a little old on long trips, but I don't have a 4:1 TC and I appreciated the lower gearing for offroading. I'm currently 1 gearset below that now due to an axle swap. There are days I miss my touch lower gearing, and a lot of times I like right where I am now. It would be a similar thing for your situation between 4.56 and 4.88. You'd really be fine with either, it just depends on if you want to lean a bit more aggressive or not.
**if you ever tow anything like a trailer, I'd go with 4.88s
