The rubber thumb rest has come off my Canon 550D, but I still have the original piece. There are small holes under it, so I’m concerned about liquid adhesive getting into the camera body or making future repairs harder. What type of adhesive or tape is best for reattaching this part safely?

Both the official Canon replacement part and many of the third party replacement parts offered on eBay show 3M tape already attached to the back of the replacement grip.
I'd follow their lead as others have suggested and use 3M VHB, 3M 300LSE, or 3M 200MP (for other grips on the 550D), as it seems to be what Canon and third party makers use. Or you could buy a replacement grip with the tape already cut and fitted on the back of the grip for $5-20 USD. This listing even offers free plastic pulling tools to remove an old and cracked grip from the camera.
There are also anecdotal comments posted in places like DPReview forums that super glue/gorilla glue works as well. With any liquid or gel type glue, one should take particular care to not allow any of the glue into the holes in the camera's body panel. All in all, though, adhesive tape seems to be the better solution.

Use double-sided adhesive tape rather than liquid glue. That’s how Canon and many replacement grip parts are typically supplied, and it avoids the risk of glue running into the holes or damaging the camera body.
Good options mentioned were standard double-stick tape or thin 3M adhesive transfer tapes such as VHB, 300LSE, or 200MP. Trim the tape to fit the thumb rest, apply it carefully, and press the rubber back into place.
Avoid permanent liquid glues such as super glue, Gorilla glue, wood glue, or similar products. They can seep into openings, may affect plastics or rubber, and make future grip replacement or repairs more difficult. Rubber cement may be removable, but tape is the safer choice here.
If the original thumb rest is worn or no longer fits well, a replacement grip piece is another good option since many come with the adhesive already attached.
