Wonderful question. You describe two levels but there might even be three
- What parents ask for or command
- What parents want or hint
- What parents need but don't ask/hint
I believe the answer is your level 2 but in certain cases even level 3.
As brief context, the mitzvah of honoring once parents comes from two psukim
The Gemara (Kiddushin 31b) describes honoring as giving them to eat and drink, assisting them to dress, helping them enter or leave a room or building, and in general taking care of their physical needs. Fearing parents includes not sitting/standing in their place and not contradicting their words.
The Rambam writes (Sefer Hamitzvot, positive #211) that a son should serve his father in the same way that a servant serves his master ("We should think of them as we do of someone who people fear, and who is able to administer punishment such as a king; and act towards them as we do with someone we fear can do us harm"). How does one behave with a King? Does one wait for him to ask? No, we try to understand what they need and give it to him. Either because of love of for fear of punishment. From there we see we should do what parents want even without explicit command.
Moreover in the Gemara above that R Tarfon would bend down so his mother could climb on him to go to bed and whenever she descended from the bed she would descend on him. And the Sages said this was not even half of the honor one should have for his parents. It is hard to imagine that R Tarfon's mother asked that from him. From there we see that one should indeed figure out what parents need and be ahead of them.
But there is one more level. To do what parents need even against their command. Sefer Chassidim (cited in Nishmat Avraham YD 240:4) writes that one is not obligated to listen to his sick father who was told by doctors not to eat a certain food if he asks for that food, even if he threatens not to forgive his son in this or the next world. Similarly the Schach (YD 339) writes that if a dangerously ill parent demands to be told the nature of his illness, one may not tell him. From there we see that we should do what parents really need even if they ask otherwise.
