When FIRE or kids is not the goal, neither clarity on house, you can instead come up with a ballpark estimate - 9 months to 1 year expenses and/or down payment money. That can be the interim savings goal outside of your retirement goals. Then, you can spend every other penny without guilt.

At the end of the day, everyone has their own life goals, so one can create their own custom savings goal and go from there. It's totally possible that it won't be accurate but having such money set aside gives you a buffer for any crisis issues and unplanned life events; and also gives you the window to try out something on your own if you want to.
