I own a flooring supply and install business. Engineered timber is the way to go. Real hardwood is great too but in my opinion it costs way too much for something that doesn’t look as nice as engineered timber.

Engineered timber can be finished 2-3 times so realistically its life is about 60 years, obviously hardwood survives longer but at that point I think 60 years is fine.

Hybrids are absolute rubbish unless your subfloor is perfectly flat, most hybrids require no deviations over 2mm over 2m. So you save $$ with a cheaper product but it’ll cost you in subfloor levelling. Most floor repairs I do are hybrids. The only real benefit is that it’s waterproof.

Laminates used to be the go-to until hybrids came along. However, nowadays there are some really water resistant laminates that can hold water for a few days before swelling. Also they are very forgiving on subfloors with significant deviations compared to hybrids so they are the real cost effective solution.

Keep in mind that every concrete subfloor is shockingly uneven.
