Was Paul in doubt about things?

Barnes':
Cambridge Bible commentary:
Geneva Bible:
Vincent's Word Studies:

1. Barnes notes are about his opinion of Ro14,15. 2. Cambridge Bible commentary's discussions on grammar do not change my views but reinforce them because they indicate these Ro's hold varying opinions on topics . 3. Geneva Bible is an opinion of the reader. 4. Vincent's Word Studies discussions on grammar are much like Cambridge Bible.

My conclusion then is the apostle is saying that the church is to receive as brethren even those who may be weak in the faith, who may have certain scruples or opinions concerning things not spelled out in God's Word or by the doctrine of Christ, but we are not to receive them for the purpose of haranguing them or "arguing" with them, lest they become confused and confounded and possibly stumble.

The passage does NOT say or mean "ignore differences in doctrine" or "there are a few key major doctrines we agree on as essentials and everything is nonessential so let it all ride". Rather, new converts are not to be introduced to the assembly to be critically examined (and found wanting) in their immature opinions and scruples. Instead, they are to be received as brethren (since they have in fact been converted) and any deficiencies in their opinions are to be taken care of through the regular teaching ministry of the church. No putting newcomers into the hot seat or ganging up on them to put them on blast and argue with them about stuff that is literally not solid apostolic doctrine.

Your last 2 paragraphs are 1. an opinion of the view you hold. 2. An explaining away of what Paul plainly says. You say The passage does NOT say or mean "ignore differences in doctrine". When Paul tells holders of opposing conclusions to accept one another, what else can be concluded but that he means they should accept differences in doctrinal conclusions?

I repeat what I've said elsewhere: Paul does not indicate that he is addressing new converts unformed/not matured opinions when using the word weak. What he says can be applied to the Christians of any maturity.
