There's a little section on the Gardeners World main website, with jobs for July. I know it has a few, including carrots, radish, wallflowers, forget-me-not and delphinium, but there were some others too 🙂
There are quite a few perennials and biennials that can be sown now for next year. Plants like foxgloves that are finishing will be dropping their seed now, so that's a good indicator that it's the right time to sow them.

You are probably safe with most biennials, except very early flowering ones, as they would naturally drop their seeds about now, or in a month or two. Being a little early is not likely to cause a problem, but check hardiness in anything you need to overwinter outside. You don't want to end up with a load of little plants that need cosseting
I've had a dig among my seed packets and found some foxgloves, sweet williams and wallflowers that I am going to try, even though some seed is not new.
You might have some luck with wallflowers @Buttercupdays - I found some old packets of seed and bunged them in earlier this year expecting nothing - doing very well. "Sow by" date of 2016!
