Insane recommendation for complete time off (baring injury). Hell, I tore my pec, looked like a panda with black splotches on me, took 4 weeks off and then got back at it (lower body carefully and rehab for upper until I can build back again)
There are other ways to recuperate - and better or less damaging ones: lower total volume, decrease frequency (lowers weekly volume), lower intensity (% of 1RM ie lift lighter weights) - frequently applied in combination (though lower volume/high intensity is for peaking just to note).
For a nice mental break I like to focus on core lifts, but nothing super heavy, moderate volume, and reduced frequency. This is more a maintenance phase and inside there I can prioritize other aspects of training whether that's cardio, skill specific, or screw it - work hard on a hobby, learn to play an instrument, push hard on career or other life aspect.
Toggling on/off 100% or 0% for long periods is a simplistic and generally shit approach to anything in life that you actually care about. That said a nice vacation can be earned, warranted and helpful.
