Sorry, propaganda from sellers of Lithium batteries.
1) Depends on charging circuit re how Lead Acid charge. Also if nearly fully charged it doesn't matter.
2) "LiFePO4 is that they will accept whatever charge you throw at them." Totally untrue. Once they are charged there is zero charging. Lithium battery life is longer if not absolutely fully charged.
The Lithium tech batteries are less recyclable, use more resources to make and fire / explosion risk is very high if charging HW or SW fail. Lead Acid much safer.
If your batteries frequently get fully charged when loads of daylight left then:
1) If you don't run out of power in dark, you have more batteries and panels than you need.
2) If you do run out of power in the dark, then you need more batteries.
