My rule of thumb is simple: whatever people did in the last decade who hold up in the rental or home sale market (clean styling bathroom and kitchen remodel, hard wood flooring, AC, quartz countertop), is a good thing. Those who falls apart and people reduce / ignore how much the owners paid for back then (swimming pool, jacuzzi, walk in bathtub, fancy cabinet, fancy countertop), is a no go.
I don't like to DIY a lot of things that show up as ugly. Sure I can probably spend 5x the time to do tiles and end up looking like a new buyer want to redo it again, but I might as well not do it in the first place or just pay a pro to do it right. To me it is much easier to look for homes that already have everything I need and compromise than to DIY things that I might fail on. I can do toilet and paint but I won't touch tiles.
Also whoever said you should pick hardwood / laminated wood over laminate flooring in kitchen... I will ignore the rest of your advice.
Personally I prefer quartz over granites for ease of maintenance but that doesn't mean all granites are bad (I just hate a lot of the styles out there, like my parents'). I would never do marble in my own home or rental property.
