Conclusion of the Sugya: Following Chumras of Two Different Opinions

Clarify the two different opinions when a we follow the rule ספק דאורייתא לחומרא ספק דרבנן לקולא and when we say following the chumrahs of two different opinions is considered foolish.

which brings a machlokes between when the day is considered over in regards to until what time a person can daven mincha and what time a person could start davening maariv.

Rabanan – Day ends at shkia (sunset) 

Rebbe Yehuda – Day ends at Plag Hamincha (two and half halachic hours before shkia) 

The Gemara concludes one could follow whichever opinion they decide. 

Could a person daven Mincha after Plag hamincha and then daven Maariv immediately following (before Shkia)? 

Would it be permitted if it was two different days?

Learn “תוס’ דף ו: “ומי

According to the conclusion of the Gemara: When is a person considered a Rasha for following the leniencies of two different opinions? (two reasons of the Gemara)

See גמרא ע”ז דף ז. “ת”ר הנשאל  (twelve lines from bottom of Amud) until “ת”ר ” (four lines from the bottom) which brings the rule ספק דאורייתא לחומרא ספק דרבנן לקולא.

https://hebrewbooks.org/shas.aspx?mesechta=27&daf=7&format=pdf

Major Questions:

Based on the above rule according to the first explanation of our Gemara why before the בת קול ruled the halacha like beis hillel was it left to the volition of the individual to decide to follow beis hillel or beis shamai. Why were they not bound by the rule ספק דאורייתא לחומרא ספק דרבנן לקולא ?

According to Rav Shizbi explanation one can not follow two chumrahs of two different opinions if  they are סתרן אהדדי. Based on the rule of ספק דאורייתא לחומרא I should be obligated to follow the stringent opinion in both cases?
