LFP and lead acid will happily work with 14.4V absorption and 13.4V float. I expect a Victron Cyrix would be fine as far as charge profiles are concerned, but there are factors to consider if you wanted to run LFP and LA in parallel. Best bet is to not do it. If you need LA for engine starting and alternator charging and LFP for domestic power, fit a DC-DC charger to charge the LFP from the alternator.
