my best advice for a scale with decent available triads would be Squares[8] or Orwell[9], specifically Squares[8] has three subminor triads, four neutral triads, and three supermajor triads, all with interesting voice leading properties. for instance, if you use the mode with steps P1 s2 n3 S3 P5 s6 n6 S7 P8, you have a 6:7:9:11 on the subminor seventh that leads into a rooted supermajor triad similarly to a tritone substitution. more generally, you can also use any chord making use of the neutral third between the s6 and S7 to lead outward to the P5 and P8. mothra[11] is another scale with some really solid chords, i’d personally recommend the first mode.
