You don't need prefix translation to use a ULA prefix. You just configure both the ULA and the ISP-delegated GUA prefixes simultaneously.

Right, the ULA prefix theoretically has lower preference, so it should only be selected to reach hosts in the LAN and the GUA for everything else, but I don't know how well softwares handle this in practice.
Source address selection is usually left to the kernel, so that part should be okay. It'll pick a GUA source for a GUA destination unless you've changed the labels with `ip addrlabel`.
