Beyond that, I think you start to have to consider multi-year strategies, like doubling charitable contributions and even property taxes, to be able to itemize every other year, or maximize the impact of itemization. This doesn't have to be as extreme as it sounds: one year, take care of both in January, then take care of the next year's early, in December. That can minimize the unevenness for charities.
Also, if all your contributions are max and pretax, consider what your tax bracket will be in retirement, particularly after RMD's kick in. You may be doing yourself a disservice, if you don't have a specific spend down / Roth conversion strategy in mind.
I have found a healthy dose of good ol' taxable investment account has performed very well in FIRE. As MFJ, taking a standard deduction, I get nearly $100k at 0% LTCG--basically Roth-like. (The party will end when I begin IRA withdrawals and take social security) I do have some interest income, but I true up my nonrefundable credits and ACA subsidies with a partial Roth conversion every December to take the edge off RMD's.
