Many people would say it's all of those, since Jesus recommended all of them to his followers.
None of the churches that teach that doing good works counts towards achieving salvation can identify which acts exactly should be done, how many of them are needed for salvation, or if some are worth more to God than others.
But in the verse from James that you posted, he is not recommending good works as more important than Faith or equal to Faith, but saying instead that if one does really have saving Faith, he will naturally do good. If he does not perform good works, then it isn't really Faith.
I respectfully disagree my friend because James said that faith can be without works and Paul also pointed out that faith can be without love and which is also not profitable.
“If I speak with the tongues of men and of angels, but do not have love, I have become a noisy gong or a clanging cymbal. If I have the gift of prophecy, and know all mysteries and all knowledge; and if I have all faith, so as to remove mountains, but do not have love, I am nothing. And if I give all my possessions to feed the poor, and if I surrender my body to be burned, but do not have love, it profits me nothing.”
1 Corinthians 13:1-3 NASB1995
Having a faith able to move mountains would be a saving faith but without love it is useless. Personally I think James was making the same message given his statements in verses 14-17.
“What use is it, my brethren, if someone says he has faith but he has no works? Can that faith save him? If a brother or sister is without clothing and in need of daily food, and one of you says to them, “Go in peace, be warmed and be filled,” and yet you do not give them what is necessary for their body, what use is that? Even so faith, if it has no works, is dead, being by itself.”
James 2:14-17 NASB1995
