The p K a of the C H X 2 group in a dicarbonyl compound is roughly 10, whereas the p K a of a carboxylic acid is roughly 5. For example, dimethyl malonate has a p K a of 13 whereas acetic acid has a p K a of 4.7. So, the C–H bond acidity is not likely to be under consideration in any of your compounds.
