So, your most comfortable option may be to take the EL direct from Heathrow to Whitechapel, and then step-free change there for 2 stops on the District Line to Tower Hill. The Elizabeth Line is very comfortable and will feel quicker than the Piccadilly Line, albeit is a bit more expensive. You would definitely get a seat from Heathrow.
(Alternatively, you could change from EL at Farringdon or Liverpool St but the latter is probably a longer walk. Citymapper recommends the Whitechapel change.)
Farringdon or Liverpool Street to Tower Hill would also necessitate waiting for a Circle Line train which are only every 8-10 minutes or so. Elizabeth Line East to Whitechapel and then back into town 2 stops on District is probably the better option.
Elizabeth Line platforms are
very long and Whitechapel only has an exit at one end so make sure you sit in the right place to avoid excessive walking. Someone has helpfully documented the best places to sit for a quick exit at each station between Abbey Wood and Paddington (Citymapper App may also have this?).
