Yes to yarrow, daisy, birdsfoot trefoil, clovers,
if you get buttercups get the meadow ones, Ranunculus acris, not the creeping ones but they do need a bit of height before they flower.
I wonder if your bugle is self-heal, Prunella vulgaris, that flowers in my lawn between mowings.
I'm not sure if thrift and scarlet pimpernel would compete but worth a try
Also green in my lawn but won't flower if mowed are yellow bedstraw, marjoram, agrimony and cat's ear
Prostrate thymes and small mints also worth considering
