Is the meaning of your statement, "Refraining from delving into this حديث and similar ambiguous narrations (متشابه الأثر) is more preferable and safer," that one should believe in the wording of the حديث and entrust its meaning to Allah, or that a Muslim should be aware of the scholars' opinions on it without choosing any particular view?

A Muslim is not required to know the sayings of scholars concerning this hadith, and there is no sin upon him if he is ignorant of them. This is something where his ignorance is excusable. This hadith is one of the hadiths concerning attributes, and it is preferable not to delve deeply into it, but rather to suffice with restraint and submission, as excessive inquiry into it only adds confusion. It is sufficient for a Muslim to emulate the Companions, who did not undertake to delve into matters that were not made clear to them. Sheikh Al-Uthaymeen holds that people, regarding the chapter of Allah's Names and Attributes, are divided into three categories: one extreme that believes Allah's Names and Attributes should not be explained because they are from the ambiguous (mutashabihat), another extreme that delves deeply into every aspect of them, and a third, moderate category that teaches people what they need without delving deeply or undertaking excessive effort. This last opinion is the most preponderant.
