Everything looks pretty good. You have a few options that really depend on your goals/future plans.

- Increase 401k contributions. This makes the most sense if you don't plan to retire early. You can also consider backdoor roth.

- Increase brokerage contributions. This is ideal if FIRE is on the table and you want to set aside money for medium-long term bridge account. Index funds and/or bonds are both good options depending on your risk tolerance.

- Build CD ladder. This would work great for money in the 3-5 year timeline. Rates are currently great and would be locked in.

- Start a 529 or other savings vehicle/educational expense fund for kids. There are a lot of options here so do some research.

- Keep additional savings in HYSA. Rates are decent but not guaranteed. Cash position is good if you're concerned about a potential recession or want to keep options open (both for investments or fun). You could splurge on a nice vacation, a few lifestyle upgrades, look into alternative investments like REITS, rentals, etc. You've done all the correct things and deserve to enjoy the fruits of your labor!
