I'm thinking two different things. The holes in the basil leaves look like the kind of damage that slugs leave behind. The little scraped looking places on the strawberry leaves look like the marks from some piercing/ sucking insect, like maybe thrips.
If you type slugs or slug control into the search box at top left you will find a ton of stuff written here about them, since they are a very common garden pest. I use diatomaceous earth against them, but there's lots of different things you can try (probably all of them helpful and none perfect). The diatomaceous earth is pretty effective, but has to be re-applied after rain. Since where I am it has done nothing but rain all summer (sorry all you people in drought; if I could send you some, I would), I gave up on the DE. You will never see the slugs unless you come out late at night with a flashlight and check under sides of leaves and where leaves join stems.
Thrips are teeny, tiny, barely visible insects. If you shake a leaf over a piece of white paper, you may see them looking like tiny bits of thread. You can treat for them (organically) with Neem oil, Safer's insecticidal soap, or Spinosad.
It helps if you grow nectar bearing flowers in your garden to encourage the beneficial insects like ladybugs, lacewings, minute pirate bugs, etc. All of those prey on thrips and other pests in your garden.
