Hi, welcome
Primarily we are an anonymous mental health support and advisory forum with members and community champions that offer guidance to those that need it. I'm not sure if you realise that. Regardless I think I can give some ideas.
In effect it seems you are seeking a non romantic soul mate. This type of friend in my lived experience isnt the sort of person you find by looking for them, more a drawn life of common interests that usually comes about after meeting many people.
I've longed believed my wife of 15 years and I are soul mates, brought about with those common interested- love of animals, camping, writing, my daughter that my wife knew since birth through family and so on. So I suggest listing all your interests like sports, hobbies etc and attending those places to mix in with those people. My one concern is that often such a person can be looking for something more or less of the relationship eg more romance or less so than what you seek yourself.
I wouldnt rule out computer dating, that how my daughter found her husband and they are very happy. It's how you control those apps that matters, stipulate exactly what you want.
Good luck
