401k Distribution Strategies

Any guidance on 401k distribution strategies?

I seek guidance on 401k distribution strategies to include Roth conversions.

More specifically, I seek 401k withdrawal tools which model withdrawal strategies that would include Roth conversions or other concepts that consider loss risk, tax liability, inflation, etc.

I get the general "4% + inflation factor" rule of thumb. But seek more detail.

ESPlanner appears to give me a target withdrawal amount. I'd like to take it further to consider smart strategies for what/how to withdraw from where.

Any suggestions?
