The Kenshin animated series skips most of the hyperviolent stuff and starts after the war. You could start with that show, and watch the OVA later when they are more mature.

Agreed on OG Dragonball. My son showed interest in DBZ, and I thought it might be good to go back and rewatch the series to get caught up. I started my own rewatch and was shocked at how sexualized it all was, especially given the ages of the characters. And it's not even like side-plot fan service you can skip. Bulma, a minor, is flashing people left and right to get what she wants, including obtaining Dragonballs.
