My garden did not look like this before I went away!

Why oh why do I go away? I’ve been to Cornwall for 6 days and left my garden in the capable hands of my dear old dad. He came to water once!!! When I questioned why he said because it had been raining 😩Bless him. When I left last Sunday it looked beautiful!
Anyway, I’ve lost hanging baskets, in as much as a good soaking won’t revive them, sweet peas (sown from seed last October 😢) and possibly through no fault of my dads, the borders looked awful. Perennials such as geranium, Astrantia, geum, nepeta etc. looked messy and straggly. I’ve cut everything back this afternoon and whilst it looks a little tidier, there are obvious gaps.
Can anyone recommend any good, (preferably) pollinator friendly, fillers that will last through to late autumn/first frosts? I’m not the biggest fan of rudbeckia and echinacea. They don’t have to be perennials, just something to brighten everything (including me) up a bit. They’ll be in full sun and I prefer pastels to bright colours but that’s not that important.
Thanks in advance everyone 👍🏻

What about shrubby salvias ? Leucanthemum daises perhaps?
Few more ideas here

Take a look at bulbs too, as it's coming up to the time for buying autumn planted ones. There are a few which will flower later in the year, and will give height. Peter Nyssen's site is a great one to start with
I live in west central Scotland - not where that photo is...
I am trying to look on it as an opportunity to buy new plants when I get back😕
