Afternoon all. Looking for some advice on woodworm tracks in an old elm slab I’m turning into a coffee table. Took me a week to flatten with hand planes and now find lots of tracks on the surface. What’s the best way to hide / fill / turn into a feature?

I would say to begin with treating the elm with a suitable woodworm treatment as it the w/worm may still be active Putting any other wood inside your home or workshop at risk of infection. As for the damage already done then either keep planing until it’s removed or fill with a suitable filler or at worst just live with it ( use the best face for the top )
 
I had similar some time ago and would definitely advise against keeping going from my experience, the tracks were definitely 3D and kept going through the wood.
Trial and error lead to this that worked well for me:
In my case it was flooring and I used a mix of wax (beeswax not mineral) and sawdust from my sanding and some pigments and lime to colour match and fill the tracks.
I found I became adept at making up small batches and varying the colour to the changing patina of the wood.
I scrapped off excess wax so the surrounding undamaged wood was bare and left it a few days for the wax to harden. I then waxed the whole top surface of the board with three lagers of clear wax with a day between each.
The end result was near invisible and I much preferred the look and feel of the wax finish over varnish.
I was amazed how durable it was.
The result was still good several years later when I moved, with occasional repeat top waxing. No loss of filler from the tracks, still waterproof and coping with heavy traffic.
This might sound well OTT for a floor, and it was, but I was renovating a Georgian house and didn’t want my initial daft newbie mistake of sanding the boards to tarnish an otherwise good restoration.
 
I'd cut out the wormy bits and see what I could make from the leftovers.
 
Thanks for your comments. I opted to fill them a mix of sawdust and glue. Turned out quite dark. Hopefully the wood will darken once the finish is applied. I’ll post pickies once finished.
