Hi and welcome!
The DSLR platform is just about dead now, and the main effort and new developments for both bodies and lenses are with the R-series Mirrorless Interchangeable Camera (MILC) platform. The camera you have is an APS-C crop-sensor model, so it would make sense to choose a similar style camera on that platform.
The R-series bodies are a major step up from what you are using. They have much better sensors and processors, they have face and eye detect and tracking and the top-end ones have In-Body Image Stabilization (IBIS) that enhances the stabilization from some lenses to make hand-holding even better in low light or with long FL lenses.
The models I would suggest you consider would be the R7, R10 and R50. There is a R100, but it is not as good as your current camera for multiple reasons. I personally prefer the R10 of the bunch as it has a sensor with fewer MP and that means it works better in low light and it also will focus and track better than the higher MP R7.
You can use your current EF and EF-S lenses on those bodies with no issues via the Canon EF-RF adapter.

You can browse the current selection of bodies from Canon's Refurbished shot, which offers over-stock but new, open box but unused, demo or show units 'good as new' with a Canon warranty, and some savings:
Canon Mirrorless APS-C Refurbished Cameras There is a good deal with the F10 and the excellent walk-around lens the RF 18-150mm. This is a native lens for the R platform and does not require an adapter.
If you really want to move up a level, consider selling your existing camera and the two EF-S lenses so you can fund the following full-frame cameras:

This is a prosumer body - superior build, weather sealing, IBIS, top of the line focus and Face-tracking, high end sensor with excelling ISO performance and top-end processor. It's controls are highly customizable and it will perform well with future high-end RF lenses.
Pair that with the excellent RF 24-240 IS USM super-zoom lens and you will have a serious kit that can be expanded later with RF glass.

Here are some sample images with that lens on R6 bodies. For most of your photography, this would be a single lens that does a lot, very well.

I love this lens and it punches way above its price point.
