I truly believe that we are seeing something amazing beginning to unfold in the Judiciary branch of government. It is true that the over the last 4 years the Trump administration has been jamming as many conservative judges as they possibly can, but it is becoming clear to me that the Judiciary is starting to really take it personal that they aren't being seen as a 3rd branch of government in the grand scheme of checks and balances. Republicans keep chirping over and over that it's all going to work out because the courts are going to rule for them. The tone, however, is more of a "they owe us, they're our stooges and will do our bidding" rather than "we have a strong case and the court will see it that way."
Just look at the Abbott early extension ruling. They didn't even follow the proper procedure or address why the filing wasn't timely. Did the Texas GOP learn their lesson there? No, they did not. They challenge the Harris drive-thru and the first question from a very conservative judge was "why wasn't this in front of me two weeks ago?" They didn't address it in their motion even though it was strongly hinted by the Texas Supreme opinion that it will be an issue. And that being the first question was a huge, blinking road sign from a conservative judge saying "GUYS, ADDRESS THE TIMING ISSUE" and they completely ignored it. Didn't even try. I refuse to believe that they aren't smart enough to catch it. It's because they know they don't have an argument. They just expected the court to rule in their favor because they are all Republicans.
Fast forward to Michigan. They plop a case down that gets immediately dismissed because no relief could be granted anyway because the counting is over, the state already issued a directive to allow poll watchers in a previous case, so the current suit was unnecessary, and there was literally zero basis for there to be surveillance video of drop boxes. The Trump attorney alleged fraud, but provided zero facts, names, or locations in which fraud occurred. He just plopped an entirely baseless, entirely moot claim on the judges desk and said "gimme," continuing the national trend of poking the Judiciary bear.
And to circle it all back to your cherry-picking issue, the Trump administration isn't even hiding it. They were demanding that the counts be stopped in states they were ahead and continued in states they were behind. They didn't even give the Judiciary the courtesy of an attempt of an ulterior motive. The just jumped into the courtroom and said "gimme." If SCOTUS was really on board with giving Trump a helping hand, the Trump administration has done SCOTUS zero favors in providing SCOTUS a foundation on which to build their ruling on. Instead, it appears that the Trump administration isn't even providing them cement to build a foundation. "Gimme." The Court doesn't take kindly to being seen as anything less than the 3rd branch of government and we're going to see that play out the rest of the way.
