Of and about sometimes interchange, but they do not do so in your example sentence. The phrase "my decision of this company" is incorrect (does not make sense) while the phrase "my decision about this company" is grammatically correct, and so would be "my opinion of this company".
Whether it is what you mean to say is less clear.
Decisions about companies are made by persons with authority to make such decisions, and "I'd like..." (or, "I would like", or "I wish") "...to hear your thoughts and recommendations regarding my decision about this company..." might be said by someone who has decided to allow, or not allow, a company to continue in its course.
Comment If you want help with wording of sentences, perhaps post questions in writers.stackexchange.
