As long as you are not adding too much cognitive load, I'm in favor of providing options that allow the user to interact in whatever style they choose.
I would design a consistent way to select any number of items and provide separate actions that can be applied to selected items, e.g. "save" or "delete". I would also include smallish action icons on each item if space allows, e.g. an X in a box to delete along with whatever you're using for save. Depending on the use case, I might also include an icon action like +1 or "move to top" so that all the interesting list items can be easily consolidated at the top of the list.

Suppose a user performs a search and is returned a long list of items. Suppose that many of the items in the list -- maybe even most -- are not going to be interesting to the user. You have an option for the user to save an interesting item. Do you also design an option for the user to grey out, shrink, remove, or otherwise de-emphasize an uninteresting item?
