This might be a strange solution but it may help: when you see something thats not a garment that you consider beautiful for whatever reason, photograph it and then use your wardrobe to try and capture that energy.
For example, I go on a lot of nature walks and something that happens a lot on my walks is that I'll see a lot of beautiful colours that I often don't see worn together, blends of textures like where the leaves of a tree meet the sky etc and so I try to capture that. Like that's how I realised that I love the colour combination of orange and grey.
To help I may then look through old magazines and cut out images to make scrapbook pages of inspiration, or if I have the influence of a particular era in mind to express the look I may look at stills of films from that decade (that's another way you can use pinterest that's not so algo heavy).
Then you just try stuff on and see how you feel, what you like about your attempts what you don't like etc. Ultimately imo the easiest way to avoid relying on algorithms for fashion inspiration is to take inspiration from things other than clothes and to practice translating the aesthetic principles into garments.
Do you like that one brutalist style building with hedges of wild flowers near the place you work? How do you express it in an outfit. Do you keep looking at the sheen of an apple before you bite into it? What fabrics might have a similar effect?
And then use the clothes that you have to try things and edit/style your looks until you get to things you like wearing.
