Dual Battery Help

I tried in the Q&A thread for the off grid engineering battery but not getting any help so try dedicated.

I have the OGE kit for dual, and trying to figure out what type of battery i should/can run.
2017 TRD off road DCSB (canadian spec comes with tow factory)

So I have the group 27F battery which I am planning on keeping until it dies, since I don't have the money right now to get two new batteries. I've heard mixed things about you shouldn't have wet cell with agm etc but then hear its fine from others that are running it with no issues so I figure I'll give it a go and if I really have issues I guess I'll need to swap.

I'm trying to figure out what battery I can run then. I know the odyssey batteries are good etc but whatever.
I've narrowed it down to three different ones (if any are good to use)
For now it will just be running some lighting four 9" round Iggycorp lights, 2 Iggycorp 40watt pod lights.
Maybe eventually run a fridge but not for sure yet and when that time comes I can always upgrade batteries.

Group 24 high performance

From what I understand the aux battery should be the same size if not smaller than my house battery or I'll run into charging issues. So ideally I was thinking of going with the high performance one above since it has the highest cranking and reserve. From what I understand the bigger the group the more amp hour I can get. So would that group 24 high performance be good to run or will I be running into issues?

only reason I'm really going with these is my sister works at head office for Canadian Tire so I can get a 17% discount, they often go on sale for $50 off and I still get that discount on top of it and they have a great warranty, if it dies within 5 years they replace it for free.

From what I could find with the OGE thread it just says what it was 'meant to run' but not about what else you can run.
