Your employer's 401(k) match is free money sitting on the table. Grabbing it beats every other use of a dollar — even paying down debt.
When your employer matches your contribution, they hand you 50 cents or a full dollar for every dollar you put in — before the market does anything. Even 25% credit-card debt can't compete with that, which is why the match comes before debt payoff.
Your only job here is to contribute at least enough to earn the full match — "100% of the first 3%" or "50% of the first 6%" are common formulas. You'll push contributions higher later, in Phase 2. And setting that percentage is the automation: from then on the money moves from every paycheck before you ever see it.
