something has moved there. are the tiles loose?
I would scrape out the old grout and match it with new, if it's hard to get out just scrape a bit to V it and apply new

Without knowing the exact install method used its hard to say how bad the problem is.
You can scrape it out but be careful not to nick the wires in the floor. Grouting will probably just crack again because you are getting movement. You could get a color matched caulk and put that on the crack and it might hold longer but who knows.
Anything you do will just be a temporary fix and it will happen again. Something is moving and will probably continue to move.

On a bathroom floor that is close to 20 years old, I would go with color matched caulk. Unlike grout, it is a bit flexible. If that crack just appeared, I would be worried about movement. If it has taken that long to move what, 1/16 inch? I would caulk it and move on. I live on a hill and over expansive clay soil. If I immediately fixed every 1/16 inch crack that shows up, I’d never be able to do anything else but home repair.
Do you have plans to remodel the bath in the near future anyway?

i wonder if SAKRETE Mortar Repair or Loctite polyurethane concrete PL S10 would be good?
I'd like to know if the mortar repair products would hold up in a grouted area?

Not really a good option.

No - I got it remodeled 15-20 years ago and that's when the tile went in.
Any ideas on types of caulk to use?
If you don't know the brand and color originally used you will have to guess. Home depot and lowes both sell color matched sanded caulk in the tile section. You can look at those and try to find one that is close. If you know the original color it might be easier to find a match but with how old it is you probably will have to just find something close.
Looks similar to mapei chamois, which has been popular for a long long time and I used it a ton 15-20 years ago, man that makes me feel old.

I agree
But unless you are an incredibly thorough housekeeper, your old grout is not the same color as it was when new so matching with the original stock color probably won’t work.
I buy tile at a tile specialty shop where they have samples of the grout installed in little metal U channel pieces so you can take a few to the job site and compare to color match. This might help when looking for a color match caulk.
If the big box store doesn’t have anything close, you might try to find a tile specialty shop that caters to pros and high end installers.
