I love proffee. I find more protein shakes too sweet, so I tend to mix decaf coffee with part protein shake, part fairlife milk. I've tried unflavoured protein powder into coffee with milk as well and it's not bad but never quite as good, lol. If you like flavoured coffees, sugar free syrups and extracts are great to change things up -- I like bourbon, almond or rum extract in my proffee, but can only handle the sweetness of the sugar free syrups if I'm using unflavoured protein powder in place of a shake, otherwise it's too overpowering.
My program had me wean off shakes and into purees (not soft food), so I had a much slower reintegration into 'actual food'. But I remember being absolutely in love my first day of purees (cottage cheese and pureed sweet potato seemed like heaven) -- and progressing to soft foods, I had chicken noodle soup my first day and not having to strain all the delicious things out of it made a world of difference. It's like a light shining down on you from above that there's an end to what you're going through, confirmation that you will be able to eat 'real food' again, all that reassuring stuff.
For soft food, definitely recommend ricotta bakes -- but since you're allowed lean ground meats too, you could adapt it into an even more lasagne (sans noodle) experience by making the tomato-sauce a meat sauce.
If you're allowed crackers yet (my program allowed melba toast and saltines early on), 'avocado toast' with a bit of cream cheese is a nice texture, or pseudo-eggs benedict: crackers/toast with goats cheese and a poached egg. I loved making chili with ground turkey and random veg, add a bit of refried beans to thicken it up and serve with a dollop of greek yogurt on top in place of sour cream.
