Thanks for those who have provided suggestions so far.
First off, I don't have a super well defined role for this tool kit. As has been noted, around town, I am more likely to call for a tow. But I did want something for when I'm away from town that might come in useful, maybe if I bent something up and wanted to try to patch things together. Sort of better to have than to want idea.
Over the past couple of weeks, I've been collecting a set of tools for the Jeep. Some I had and some I picked up at my local box stores, and a few I ordered.
In general, I wasn't looking to spend a huge amount of money as I don't intend to use them that much, so they aren't top of the line tools.
I decided to get metric sockets only for now. If I can find evidence of US sizing, I can reconsider.
I thought about the socket sizes quite a bit. I didn't want several sizes of socket wrenches and a minimal number of different drives. What I ended up doing was getting a 1/2" drive wrench with a 1/2" to 3/8" drive adapter. Most of the sockets are 3/8" drive with the big ones being 1/2". I think this works out pretty well as the 3/8" is nice and stable driven with the 1/2" wrench.
I went with standard screwdrivers in addition to a bit driver for a number of reasons. First, I've found that trying to remove stubborn screws, you really need high quality screwdrivers and fiddly things like bit drivers don't work so well. Also, sometimes the bulk of the bit driver head gets in the way. And sometimes having a big #3 comes in handy.
Note, I do have a few tools in the Jeep not included in the "tool kit". I tend to have some things that could be useful in vehicle extrication kept separately:
* hack saw
* bolt cutters
* 3' crowbar
Likewise, I have a set of jumper cables, but I keep those in the main storage compartment for ease of access.
At some point, I plan to pick up a Diablo Sport DCX INTune 1000 at some point, mostly so I can set the tire size, but it should cover diagnostics as well.

Everything fit into a small canvas bag that came with my Hi-Lift kit. Right now, I'm not carrying the Hi-Lift as I don't have a good way to carry it and good jack points.
Although I do have a couple of items like a d ring receiver hitch, a couple of d rings, etc. in the bag as well since I had room and to avoid having to find an alternate place for them.
I have a couple of recovery straps that roll up and fit in the forward nooks in the spare tire well.
I removed the styrofoam spare tire insert, and the bag fit there along with the jack, Viair 88P compressor, and a bit of tie-down rope.
