RPE or RIR are just over complicated ways of saying “don’t go all the way to failure”.

Just go lift, aim to increase on last session, and if you don’t increase load just do a bunch of similar work without going to failure (1 or 2 reps in the tank).

Working up to a heavy single is a great method but if you don't lift at that intensity often then your warm ups serve as a good indicator about your lifting ability for the day. Even as simple as a 50% of weight to be lifted for 4-6 reps then 75% predicted weight for 2 reps then 90% for 1. You can then use how those last 2 sets felt to dictate whether you will be lifting as predicted, lifting more or whether you will have to reduce volume for the day as you are feeling fatigued, not as strong etc. Always reduce volume but not intensity.
