epoxy to use when rebedding hardware

Spyderweb

I have some water leakage in a handle on the transom door, and in the starboard stern cleat.  I understand the importance of drilling the holes out larger then filling with epoxy, or gouging out some of the core material (as with a bent nail on a drill) and then filling with epoxy protect the wood core from future leaks.  What I'm not sure of is how specific the epoxy needs to be.  For example, I have 3 different epoxies at home now.  They are JB Weld Quick Set, HFT Instant Setting Epoxy Adhesive, and Marine Tex.  

I was leaning toward the Marine Tex because it states it's more of a putty consistency and might be easier to work with on a vertical surface.

Are any or all of these suitable?

Is the area around the holes that damaged?

There's a little bit of soft wood in the 3 holes for the handle.  Haven't removed the cleat yet but don't expect to find much rot there based on viewing the back side of the cleat.

I installed a new transducer on mine this spring and drilled all holes to 1/2" then filled with Marine Tex then drilled for the screws and used 4200 on them. The only problem I had was the consistency was too runny and it kept oozing back out. I had to sit there and keep 'squeegying' it back in until it stayed but other than that I had no problems.

You can use butyl tape too

+1 on butyl tape.

Example:

Agree on butyl tape to seal, but the question is on epoxy so I assume your looking to fill the holes and then re drill? If so west system epoxy would be the best for filling holes.
