[irremediable]

The KBoges channel is generally very good. I'd take a lot of care in building up to daily training, though; you only get one body, and if you injure it you may never be the same. He does emphasise this in his videos, but in his shoes I'd be reluctant to even suggest daily training to people, because some significant minority of them will always go too hard at it and wreck themselves.

My preferred style of "everyday training" is strength training every few days, cardio most non-strength days, and walking a minimum number of steps every day (cardio counting towards it).

Push + pull + lower is generally enough to get fit and healthy, yes. It could be a good idea to split it more like push / pull / lower front / lower back, because things like squats tend to work the quads way more than the hamstrings or glutes.
