You could try a shelf instead. That allows for some of the low end to stay present without cutting them out completely. I only use a HPF to remove unneeded low end noise but if you're trying to preserve the tone then either that peak or the shelf should do it

HI Eli
There is no absolute answer. You can use a low cut, you can use a low shelf, you can use a bell......does not matter. What does is how the vocal sits in the track. Sometimes you might need a thinner vocal to sit right in a dense and midrange forward mix. Other times you might need a fuller vocal to have the presence in a very delicate or sparse kinda track.
What I would suggest doing is to use your ears and not rely so much on the graphics displays of the EQ....we often trick ourselves in or out of decisions by using our eyes instead of our ears.
I am not sure if this will work for you...what I do is basic rumble clean up at the start of the mix....meaning I use a low cut to get out totally useless info...like under 50hz to start.
As I get into the mix, and turn my attention back to the vox, I will close my eyes or have no visuals and roll off some more low in the vox...I do this by rolling until it sounds thin then backing it off till I hit a good spot.
Personally I tend to do this part BEFORE compression....but I do understand wars have been fought over which comes first...eq or compression LOL.
Finally, if it is just a tricky vocal or I can not get a static spot to sit my low cuts...that tells me it is time to use a MultiBand Compressor......that way it will do the job when needed and the rest of the time get out of the way.
Hope this helps and good luck

Hey man! The best way to control your Lows and low-mids are cutting the low end between 0hz to 90hz, usually we don't cut more than that on a male vocal, to control your low-mids add a Dynamic EQ between 120hz to 360hz or a multiband compressor. Also experiment adding mid-highs that is usually masked by low-mids.

I cut the low end very carefully, so it makes almost no audible difference, just to avoid build ups in the mix.
I guess, as far as I can understand your issue, that a Multiband Compressor could be great solution. Just select and compress only the fundamental of the vocal, then adjust the volume. That will get you into the ballpark, so its more controlled and less boomy, however without sounding thin.

While there's no answer will always work for any Q&A, it's good to consider is those tutor's background you watch.
I noticed that some genre has definitely their own sweet spot. And some engineers are sharing very useful template for that , for example Hardcore Music Studio who's doing great on Catchy Metal Core type of music.
I think that's worth to follow as a training.
But then if you wanna be different or unique, of course you wanna try everything.
I think some or many tutors online are just trying to get attention because everyone wanna do shortcut.
Then again, template itself isn't a bad idea. You just wanna find cool producer who can give you cool one.
Peace
