In this word confusion, as vs for, both are causal conjunctions and prepositions.
As, usually followed by a noun or a gerund, is commonly used to indicate a role, a similar comparison, capacity, simultaneity, or causation.
For, usually followed by a verb, is used with a period of time in the past, present or future — three years, four hours, ages, a long time, months, years, etc.
For is also a substitute for because (a bit more formal and less common in everyday speech) and is reserved for poetic usage, as in “Let us eat and drink, for tomorrow we die”.
For may also be used to introduce someone who is receiving something, to an exchange, in multi-verb forms, to talk about the function of something or how it’s used, and using for + -ing to talk about function, explanation, or the reason for something. We also use for + infinitive to express purpose or intention.
