Like the sibling comment said, org-deft is pretty fantastic. I have a single folder with many many org files. I have tags in them for general attributes and link/backlink via org-roam so I can instantly get a bird's eye view of which notes relate to which. While actually editing, org-roam has simple double-bracket syntax that auto-completes existing filenames. If filename doesn't exist, it is created when the link is accessed first time automatically. Hierarchy gets established automatically as I track back links, or via org-roam graph view. But really, once I started linking notes extensively (because its so easy with org-roam), I realised that my structure ended up mostly as a graph rather than tree. However, org-mode itself has excellent tree style syntax within individual file, which comes in handy. Searching/analyzing can be done either from withing Emacs via elisp or externally via ripgrep/fd (I'm still noon at elisp)/
