Is there a Framework for money allocation after 6 month ER fund is established and HSA is maxed?

Forgive me im learning and curious but if i understand correctly focusing on maxing things like Roth and SEP IRAs should be considered once youve got a decent footing financially but im curious on if there is a percentage or framework for those who want to move forward with building for retirement while also remaining agile?

In other words, would it also be a wise strategy to invest in more liquid assets (Bills,increased hysa) to potentially take advantage of market drops or even buffer small, unexpected emergencies as you progress towards retirement at a percentage or do you strive towards retirement goals at 100% because you have the 6 month buffer?

Hope this makes sense.
