If I had to rank the options:
Alonso - but he's going to be prohibitively expensive
Suarez - only if they can move him to 1b or if they don't re-sign Breggie
Schwarber - he's not leaving Philly though
TO - could be a cheap DH option
Naylor - don't like his fit at Fenway TBH
Ozuna - down year, overall decline?
Gary Sanchez - wild card add by me, if made into a DH at Fenway he'd hit 30 bombs
Muncy - don't think it'd work here
Tucker - like the player, but too much money and the Sox are set in the OF
O'Hearn/Yaz/Bichette - N/A, don't have the power profile needed
