Don't meta-chase. It's dull.
^ this. especially as by time you buy, assmble and paint your model chances are a new
FAQ will be released that has shifted the meta anyway.
that said, looking at what he has for a moment..
Indomatus includes 1 Captain, 1 Leuitenant, 1 Chaplain, (3
HQs) 10 Assault Intercessors (1-2 squads of troops depending on how you build them) 1 Squad of Blade Guard 1 Judicator, 1 Bladeguard Ancient, (3 units of elites) 1 Outriders Bike Squad (1 fast attack) and 1 unit of Eradicators (1 heavy support unit) ... jesus thats a lotta stuff I forgot how awesome this box was.
All told this is approx 1000 points out of the box. Assuming what you bought was the Marine Company Command box, that nets you an additional captain (that can work as a Leuitenant and Leuitenants are a "2 for 1
FOC slot deal") Another ancient (guys with banners are called ancients in case we're unclear

)an apocathary a company champion and 2 company veterns.
this
BTW clocks in at just under 1300 points. so to expand up to 2000 points you need another ~700 points. worth noting. although you've got 7 elites and can only take 6 so proably best to leave the veterns at home (they're about 60 points total for the 2 of em assuming you go with a plasma gun and combi-
plas) not really worth it eaither if you ask me)
So now that we know what you have and how many points to add, where to next? well let's start on filling the basic requirements.
to run a basic battalion you need 3 troop chocies minimium and you're only going to have 2 Max. so I'd start by picking up a box of your favorite troops. the great news for a space marine player is we're SPOILED for troop choice, with a grand total of 6 troop choices. So you can find whatever you fancy and grab a pack of em. I like basic intercessors, they do a fantastic job. Ohh word of warning in case you've not noticed, SCOUTS ARE NO LONGER TROOPS.
Now, once you fill in your troops. what's next well.. to taste really. codex space marine is a solid codex and all of our units are mostly good. (conventional wisdom holds that tanks over all aren't in the best of places right now but if you really wanted a Predator or something you're not
de facto throwing the game by using one)
you've got your fill of elites so that'll take additional elites off the board so terminators aren't worth looking at, nor are dreadnoughts (dreadnoughts
BTW are the exception to the "tanks are kinda bleh" trend and are actually great this edition. sadly they're elites. still might be worth ditching one of your ancients for a dreadnought later on)
I'd actually suggest making your next step the blood angels combat patrol. It's not "just for blood angels" and is a solid deal. that'll give you a Primaris Librarian (even if you don't plan to use a libby having one is a good option) a 5 man intercessor squad, a 5 man infiltrator or incursor squad, a squad of agressors, and a impulsor, solid over all box
IMHO
