I’m building tile countertops for a kitchen project. The surface as well as the front edge will be tiled. What’s the best substrate for this? I was thinking about 3/4″ plywood covered in hardie board, but I’m not 100% sure about the front edge. Since it’s only 3/4″ I’m concerned about getting good adhesion between the ply edge and the hardie and of course between the hardie and the tile. Any suggestions?

3/4" is fine but personally I like using "Wonderboard" rather than any other CBU. Just seems more substantial to me.
In the past when I've done counters with tile (granite) I made a bullnose wooden edge the same material the cabs were (cherry) with a lip ontop to cover a bit of the cbu and the the faceing to cover the fron tedge..Looked way custom....just something to ponder.
If you use a tile edge try finding bullnose specifically to cover your substrates. I have used finished edges of tile "thinsetted" (is that a word?) to the face with no problem.
You'll need to do the top of the counter first then temporarily tape the face pieces to the top until the thinset dries.
PS..be sure to use an additive rather than water to the thinset.
Have fun
BE well

3/4 ply will work. I've been known to use Advantech with good results.
For wet locations, kitchens, bathrooms, especially outdoors use "Anti-Hydro" instead of water. It is diluted with water and then used instead works in the thinset and the grout. Be careful though, it accelerates the cure time!
Works so well I've even had one job set exposed (sidewalk) for six weeks in the rain. No problem of any kind!!
BTW I get it through Dal Tile. compared to any of the other additives in this area it is a fraction of the price and top performance. Aprox $10 per gal of concentrate as opposed to $30 and up for ready to use.
