What I'm currently doing is careers with umas that I can reliably play out with good Medium/Long attributes so I can win either the Kikuka Sho or Shuka Sho. Both as a spark offer Kyoto Racecourse as a hint Kikuka offers stamina while Shuka offers wit if that matters If available, I can also win Osaka Hai for Standard Distance and Tennis Shoe Spring for Spring Runner as spark potential. I'm also doing it with umas with decent stamina/growth G*lshi, Fuku, Winning Ticket for example so running Hishi for Straightaway Spurt isn't as awkward.
I find the easiest start is pushing for race sparks and niche ability sparks Any skills I want and Long sparks that get passed is a plus during this phase, but I figured if it will ensure I don't have to, like, run the R McQueen card for more niche green skills. But any strategy will different from anon to anon, this is what I'm trying, hope it works for you or allows some other comfortable approach for you.
