For a beginner, I suggest one of the detailed exposure calculators easily downloaded from internet and printed on stiff photo paper. Print several, to have on hand. Can slip into shirt pocket. I keep one in wallet when encountering unusual indoor lighting situation.
The advantage over a meter, at least for me, is that reading a paper calculator engages the mind easier than a meter, making it easier to set exposure conditions from memory.
While I use the above method, I must admit to owning a drawer full of all kinds of meters, accumulated over 60+ years. Some of these are for cinematography, where even slightest variations of exposure ca become distractions. But got still photography, I would try calculator first.
