Mutual Funds vs ETFs for taxable account investing

This is a spin off from another thread where somebody was asking about mutual funds. A commenter noted to use ETFs instead for a taxable account as Funds have a pass through for capital gains from turnover I believe. I never considered this as I’ve always been in tax deferred investments.

I know there is more flexibility for ETF’s but is this true for index investing as well? Are there any downsides to ETFs for this type of investing that could be long term? I’m looking at investing the cash above our emergency fund into a mix of large growth and large value and wanted to make sure I picked the right vehicle and minimized taxes. Could be for 1 year or 10 depending on when we need the money.

My mix is going to be 40%MM, 30% LC, 30% LV which works out pretty well in back testing (haven’t checked too see how much overlap) and keeps me with enough cash if needed.

TIA.
