Prefer battery led's (two) for the rear. Easy to carry spare batteries, but if a USB one goes flat you've had it. I know they last a long time, but if you leave it on when at work or if you forget to recharge it, can be an issue.
And always use reflective slap bands on the ankles.
Cateye Omni 3 or 5. Put a couple on. They run on AAA batteries. A pair of rechargeable AAAs lasts approximately for ever. Disposable ones last a bit longer.
But at the rear, absolutely any old thing will do as long as you have more than one for redundancy. If you insist on USB charge just stick "USB rechargeable bike light" into a search engine. Cateye Orb maybe.
I got a Knog Blinder mini recently for just under £20. Have been pleasantly surprised by the brightness run time size and waterproofing. It is not a retina burner but plenty bright enough to get you seen.
