Since you have the ACR in place already to protect your start battery position, you will not be deep cycling your starting battery, so a dual purpose or starting specific model should do great. I will say that the dual or deep cycles are generally a little heavier built and it could be argued that they should live longer but there are loads of factors involved. Deep cycle batteries do have significantly less cranking amps so they often need to be upsized for effect starting. That is counter productive in your case.
Bob's brand advice is good and I also like East Penn products. Below are a couple more visual and price examples for you.
Something like this would fit in your current position and work well for the house.

Your motor needs a bit over 500 CCA for starting and this can easily be provide by a slightly smaller group 34 battery. It will fit a little easier (shorter), save about 10 lbs in weight, and cost a little less as well.
