Maybe your idea of what a “basic” tool should be is dramatically different than mine. I’ve never really used anything other than the open source tools (GIMP/Inkscape/Kdenlive/etc.). I don’t expect a “basic” tool for graphic design or video editing to have any templates genuinely useful to a professional. I expect automatic background removal for an image to be at tech-demo quality and require a lot of manual cleanup, and to be in general impossible in video. I expect chromakey to work terribly unless my scene is lit professionally. It looks like you could do 2D tweening animations in Synfig, but I don’t know how one would do “motion graphics” in anything. (I guess you mean that animated infographic-of-text style stuff? Maybe by making each word and animating it manually in something?)

So it sounds like you’re reaching for what are actually highly advanced tools without a lot of competitors, which may be “simple” to use and produce simple-seeming results where things “just work”, but which are themselves very complex. I’ve seen stuff coming out on YouTube now where title text is embedded in the scene, and moves with one object and has some other object pass in front of it. It’s undeniably slick, because the words are “just there” in the scene, and I can see why you’d want to deliver that to a client. But I’m also sure the tech behind it involves a team of highly paid devs, a lot of proprietary code, and probably some beefy ML models, and so nobody’s going to actually be able to use that technology for real, outside of fancy-subscription-world, until someone organizes a huge push to try and clone it. If you don’t pay the subscription, you indeed can’t feasibly deliver that thing to a client who’s asking for it.

But the good news is that you don’t need those tools for “basic creativity”. You can do “basic graphic design”, in terms of coming up with an idea for somebody’s logo or something, on a napkin with a tube of lipstick. You can draft things to professional quality with pen and paper if you have practice.

The other good news is that working within constraints will improve your creativity. Your tools and their limitations necessarily inform your artistic output. If everybody else is working in AfterEffects End of History Edition, they’ll all be making samey art that looks like what that tool makes. If you act out whatever was going to be in the motion graphic with condiments out of your fridge and edit the footage together in Windows Movie Maker, I guarantee you the result will be interesting. Will it be what every client wants? Of course not. But somebody out there wants what you can deliver.

I have no idea what you’re subscribing to for “market research” or what kind of “platform” is “speeding up” your “SEO” or “brainstorming”. If you’re a one-artist operation, you don’t need a platform for market research and SEO optimization, you need to track down your sales leads artisanally, one at a time. You personally will never be the top Google result for “graphic design”, so don’t try. You need to write your own copy, without help (and honestly you shouldn’t think of it as “copy” anyway; you just want the speeds and feeds for your services and a portfolio of your work). And if you do somehow need to brainstorm marketing ideas, you’ll need to do it the slow way, because you indeed don’t have the budget to pay to speed it up. But that doesn’t mean it can’t be done, or even that it’s infeasible.
