Make them yourself mate, it's not difficult and you'll have much more creative options.
Meant to reply but forgot being Xmas and all but for the vast majority on tracks in this vein, there are a number of common chord types and basic variations on how you voice them will give you a slightly different sounds.
For the chords, apart from Dub Tech stuff, you want 'bigger' chords than basic triads so look at both major and minor 7th chords and minor 9th chords and inversions thereof. That will give you a good starting point.
So as for some examples using C as the root note:
CMaj7 = C/E/G/B and a popular inversion is the 2nd inversion of the same chord but voiced like this: CMaj7/2nd inversion = G/B/C/E
Cmin7 = C/Eb/G/Bb or 1st and 2nd inversions respectively: Eb/G/Bb/C & G/Bb/C/Eb
Cm9 = C/Eb/G/Bb/D or a well used inversion esp in some deep house detroitish stuff etc is: C/Bb/D/Eb/G.
Cm11th = C/Eb/G/Bb/D/F not common really but I like this chord esp played like this in ascending order: F/C/G/Bb/D omitting the 3rd/Eb
That's certainly a very good grounding and you can transpose any of those chords to any root note and try out major or minor variations etc and maybe look up sus chords and find other interesting voicings too, adding notes , omitting notes etc.
For these sounds in a short stabby stylee, it's just a case of setting up the ADSR envelopes and filter envelope/s and filter type etc. Maybe some short LFO to get the shape you want, a lp filter to knock the top end off etc. But basically, you can create big pads, sound beds, bright stabby stuff etc from all chord shapes and tailor the sound as you see fit. But yeah, it's all about the chord base really and sculpting a sound from there. Sometimes you can take things further with a sampler than a synth, so you could sample off a long chord which youve made sound good and alter the envelope and filter in many ways inside a sampler and literally make tons of variations on the same sound - which is way better than using a sample pack of some short chord stab with a LP filter. You're limiting yourself from the off really
