Do not do this.
Every engine has a different redline. The redline is based mostly on piston mass, which doesn't necessarily correlate directly to engine displacement, given that it's common to have 4, 6, or 8 cylinders in a car. If you're shifting primarily based on engine sound, you can be shifting too low in one car, and then too high in another. The tachometer is a much more reliable way of learning where you should shift in any given vehicle.
Also, constantly running your car in the maximum power band--which tends to be close to the redline--probably isn't great for it.
I don't think they were saying you shouldn't ever look at the tacho, but that you should learn to be able to pick your shift points without having to look at the tacho.
As you say you do want to figure out what revs works best for a particular vehicle (having driven/ridden vehicles with redlines between 2500 and 19000rpm there I can say there is a little bit of variability to be found out there) but it shouldn't take long to figure out what this sounds and feels like for regular use.
Many cars and trucks don't even have a tach. Older Ford focus's don't, they just have a shift light. I used to drive a 70s Ford ranger that had neither. Don't get me wrong I wish it did, but it's only a nice-to-have for regular driving. Shifting off sound is fine, but it's not just sound, it's the vibrations in your seat, how the engine reacts to gas pedal inputs, etc. I only look at the tach when I need to downshift to pass.
I learned on a 2000 Kia Sephia. Five speed, little four cylinder engine, that shit did not have a tachometer. I had to learn by the sound.
Even when I got into my Vr6 Jetta, or the Nissan spec-v (which had 6 gears) I was able to adjust my driving to the car easily because I first learned with sound. You learn the engine.
Probably try learning using both tbh
