Federer finishes second in Group Bjorn Borg, behind Thiem, who also beat Djokovic earlier this week. The Swiss will face the Group Andre Agassi winner on Saturday.
The only other Italians to qualify for the elite season-ender were Corrado Barazzutti in 1978 and Adriano Panatta in 1975 and neither managed to win a match.
Federer and Djokovic will face off on Thursday in a repeat of this year's Wimbledon final to determine who else will progress from Group Bjorn Borg.
The six-time champion was not at his fluent best on Tuesday but ultimately had too much for Berrettini, who won just three games against Novak Djokovic in his opener.
Manchester United claimed their first away win in any competition since March as they beat Partizan Belgrade 1-0, but AS Roma were held to a 1-1 draw as Borussia Moenchengladbach equalised deep into stoppage time.
Pierre-Emerick Aubameyang's 58th minute goal for the visitors, given after a VAR review, cancelled out Scott McTominay's well-struck opener on the stroke of halftime but it was a game which highlighted the weaknesses of the teams.
Nadal put pressure on the underdog Italian's serve from the start but Berrettini saved six break points to set up a first set tie breaker.
The win sends Medvedev through to his fourth straight final and stretches his win streak to 12 matches.
Schwartzman reminded Nadal that danger can lurk everywhere, even from an opponent he had beaten in all seven previous meetings and only lost two sets.
Putting away the 13th-seeded Frenchman took everything that Berrettini had as Monfils, who struggled mightily with his serve late in the match, managed to see off four pressure-packed match points until the Italian finally prevailed.
