General question when running a single member LLC: how do you determine how much to take as salary versus business profit, and how does that affect your taxes?

I'm guessing tax liability is mostly a wash, as if you are taxed as an S-Corp, you pass through the profit into personal income and pay income tax on that.

That’s very much a talk to your CPA question - because it speaks to audit risk. The IRS wants to see you pay yourself a fair salary so you are paying the appropriate payroll taxes, social security, medicare, etc. The problem is “fair” is somewhat subjective and depends on the profitability of the business as well. I’m sorry this isn’t a clear answer, but it’s just not a clear matter. Seek advice and ask “how would you defend this stance in an audit”.

There is no difference in a single member LLC. All profits from the LLC pass though as income which is ultimately taxed at the same rate as salary (including SSI, Medicare, etc).
