Should I use front terminal batteries in a UPS cabinet?

Front terminal Q7.1 and Q7.2. Usually yes, where the batteries live in a rack or cabinet. Front terminal batteries connect and are maintained from the front without withdrawing the tray, need no overhead clearance so trays stack tightly, and let a technician work at normal height rather than reaching across live terminals on an upper tier. For high-rate UPS duty, AGM is generally preferred over gel for its lower internal impedance. Check the case dimensions against the existing tray rather than matching amp-hours. There is no standard front terminal footprint.
