HI NatureGirl,
Unfortunately you are right, the higher elevation trails are usually closed until mid June at least.
The earliest the higher elevation hikes open are when the transports to reach the trailheads are scheduled to begin operating. However, sometimes the trails don’t open for days or weeks later, it is entirely weather- and snowpack-dependent.
The two hikes I mentioned to Amosk will be open, here is some more detail:
A beautiful valley walk begins in Lauterbrunnen and ends in Stechelberg (or earlier, depending on your inclination). It is about 4 miles long on a wide flat path. You can go as far as Trümmelbach Falls (about half way and highly recommended for a visit) then bus the rest of the way, go as far as the Stechelberg Schilthornbahn station, about 3.5 miles total, or go all the way to Stechelberg where there is a lovely inn that serves delicious lunches. You can take the bus back from any of these stops to Lauterbrunnen. OR, in late May you may even be able to hike all the way up to Gimmelwald or on to Mürren. There is a description of all of this in the series of PDFs you downloaded.
The only walk at elevation that's pretty sure to be open is the Grütschalp to Mürren route, which you have done. But maybe this time you can see something.
Wildflowers will all be at lower elevations. The very popular "Wildflower Trail" above Mürren doesn't open until June 9.
The gondola from Wengen to Männlichen (where one begins the easy walk down to Kleine Scheidegg) is usually scheduled to begin operating in mid-May, but often the trail is obscured by snow or mud until mid June. If it is closed it is still well worth taking the gondola trip and walking around the top.
There is also a lovely easy walk along the river (starting in Lauterbrunnen) called the "Natur und Bahn" trail. You pick it up right behind (east) of the train station and follow it as far as you want. It runs to Wilderswil via Zweilütschinen, each of those segments is around 3 miles. You can catch the train back to Lauterbrunnen at either spot.
There are a number of loop trails around Wengen and Mürren that are usually open before mid-June as well. The tourist information center in the respective villages can direct you to these.
