Getting Extra Attack is also huge. I'd rush Fighter 5 ASAP to get Action Surge, Extra Attack, Sharpshooter and Fighting Spirit.
Just my 2 copper.
Eldritch Knight is also powerful due to War Magic at level 7 letting you use Eldritch Blast and follow up with your bow, but you said you didn't want anymore casters, so yeah...
EDIT: Extra stuff, given the 17 in Con I would double recommend getting Resilient [Con] at some point, to even that out but also get you that extra save proficiency for concentration. Since you have Blade PAct you can also fight reasonably affectively in melee range with a Greatsword, so GWM isn't too farfetched for the same reason Sharpshooter is excellent.
