You ask a lot of questions regarding gear, how is you current gear limiting your photography/videography? Have you checked out the lenses you are interested in-store? The pancake 24mm STM should be available in most bestbuys and camera stores. Have you checked out zoom lenses? They give you a variety of focal lengths, usually cheaper than buying a set of primes? Have you checked out the Sigma/Tamron 17-50/2.8 zoom? That one zoom lens can replace 24,28,35, 50 primes for around $300 grey market/used. Have you checked out the 10-18 STM? Should be a great budget option for wide angle shots and video, while the 55-250 STM should cover your telephoto needs for both stills and video. For someone that wants to shoot a variety of subjects, I usually recommend a zoom setup like the Canon 10-18 STM, Sigma/Tamron 17-50/2.8, and the Canon 55-250 STM. For portrait work, add in the 50 STM and the 85 USM. I wouldn't recommend getting full frame glass unless you know 100% you are upgrading to full frame in the near future due to cost, as long as you buy lightly used/refurbished lenses you should make up most of it back when you decide to sell the gear down the road, depending on condition of course.
