Unless you are an alien or have a legit medical condition this is probably pardon my french bullshit.
Choose one one of getting bigger and stronger or getting leaner. Trying to do both at once or half arsing it doesn’t work and you’ll end up going nowhere.
If you want to make decent gains fat gain is unavoidable. You could pin all the compounds known to mankind and that’d still be the reality. Doesn’t matter how your body looks right now or by the time you finish bulking. Its the body you have months/years down the track that should matter. Getting a bit fluffy now is part of the process.
The decision making process for making tweaks/changes to what you are doing is pretty simple. Is what you are doing currently working? If yes keep on going. If no think about why and make changes.
Are you getting stronger over time and lifting more weight/reps on your big compound movements? Maybe not week to week but if it was graphed over months or years the line should be trending up. If yes keep going. If no make changes.
You can have as small a surplus as you want, trying to avoid excess fat gain, but if the stimulus for muscle gains, progressive overload, isn’t there it wont matter because what little weight you gain will be 100% fat.
Probably a good fit for you at the time tho you’ll need to take a good hard look at your current progress and see if changes are required. Even little changes can enable you to continue making progress.
Doing the same thing forever will leave you looking the same. If you don’t change things how can you expect your body to change: to get stronger or bigger
