Yes, Constitution determines your HP, while Dexterity determines your Armor Class (How easily you are hit), if you are not wearing heavy armor. It is also a rather common saving throw (Many of the high damage 5e spells call for Dex Saving throws).
Therefore, CON and DEX are the tank's best friends, along with WIS for the also very common WIS Saving Throws and mainly STR for damage. Also, as a Jedi, WIS will probably be your Casting ability.
If you are going full tank, you probably don't care that much about damage, so STR would not be that high on the priority list.
