So what would be the best strategy for a single GPU miner such as myself (currently: single Vega 56 on Monero only, and single 1070 on Zcoin only)?

I've disabled auto exchange, and would like to minimise fees. It would take me about 30 days mining to reach the minimum payout amount of 0.5XMR on the Vega 56. The same time period should net me about 2 XZC from the 1070.

Can I enable Auto Exchange to Litecoin once a month to benefit from the lower transaction fees or should I just leave it on all the time? I'm not sure which coin to Auto exchange to at this point. Litecoin would have been ideal a week ago, Haha.
