For a 54-year old (that's me), which is more critical to limit the potential swim speed between flawed technique and unathletic strength?
Well, I'll actually try to improve both. However, many people around me mainly focus on swimming more laps and gym workout, while don't bother about improving their technique at all, despite their techniques being far from efficient.

It's technique in my honest opinion. But it would be better if you have mid level strength.
